Preface
Nomenclature
Errata design defects errors. These cause 80960Jx microprocessor's behavior deviate from published specifications. Hardware software designed used with given stepping must assume that errata documented that stepping present devices. Specification Changes modifications current published specifications. These changes will incorporated release specification. Specification Clarifications describe specification greater detail further highlight specification's impact complex design situation. These clarifications will incorporated release specification. Documentation Changes include typos, errors, omissions from current published specifications. These will incorporated release specification. Note: Errata specification changes remain specification update throughout product's lifecycle, until particular stepping longer commercially available. Under these circumstances, errata specification changes removed from specification update archived available upon request. Specification clarifications documentation changes removed from specification update when appropriate changes made appropriate product specification user documentation (datasheets, manuals, etc.).

Problem:
RDYRCV# Restriction During Cycles (A-0 Stepping Only)
RDYRCV# indicates that data address-data (AD) lines sampled removed. RDYRCV# asserted during cycle, then cycle extended next cycle inserting wait state (Tw). Normally processor ignores this during address state (Ta). this stepping, however, processor recognize assertion RDYRCV# during address state access prematurely terminate access. example, quad-word load (with RDYRCV# asserted during processor will erroneously take first word data during address cycle, will then read only three more words data. This will cause last word data lost, first three will corrupted. processor also incorrectly responds RDYRCV# assertion during idle (Ti) (Th) states. Under these conditions, processor will deassert HOLDA asserted), clock after RDYRCV# assertion. Hold acknowledge never asserted reasserted) until clock after RDYRCV# sampled high.
Implication: Workaround:
RDYRCV# generation logic must designed only assert RDYRCV# during either states, should used multi-master system other masters. Make sure that system implementation does allow RDYRCV# assertion during state except valid data (Td) recovery (Tr) states. Typical synchronous state logic 80960Jx described "normally-not-ready" (i.e., only asserted when system ready). Normally-not-ready logic will usually satisfy requirement without modification. Strict "normally-ready" state logic cannot used 80960Jx systems because logical sense RDYRCV# changes during recovery state. Driving RDYRCV# indefinitely during would, definition, cause processor hang states indefinitely. ready logic resembles normally-ready system, then change normally-not-ready. 80960Jx sole master, then multiple open-drain ready signals wire-OR'ed with pull-up resistor drive RDYRCV#. sure satisfy processor's setup hold timing requirements every clock. 80960Jx part multi-master system, then share RDYRCV# signal with other masters. Providing separate ready signals will prevent 80960Jx from spuriously deasserting HOLDA.

System-Local Fault Calls System-Supervisor Trace Enable
When fault handler implemented through system-local fault call, fault handler found system procedure table. other characteristics call those local call: PC.te (trace enable Process Controls), PC.em (execution mode flag Process Controls) remain unchanged there stack switch. system-local fault call 80960Jx previously mentioned characteristics, except that PC.te copied from SSP.te (trace control Supervisor Stack Pointer). This erratum could cause tracing toggled when entering system-local fault call. addition when processor user mode while executing fault handler, PC.te will restored upon return from fault handler. Little none. system-supervisor calls local-call handler instead system-local fault handler. system-local fault handlers. local fault handler required, then local-call handler place handler pointer directly fault table. other option only system-supervisor calls from system procedure table. system-local fault handlers must used, then designer should make sure that PC.te user mode same SSP.te System Procedure Table.

Problem:
Fault Stack Alignment
some situations, when fault occurs, unaligned (not quad-word aligned) fault record written stack; result, incorrectly restores arithmetic controls (AC) register process controls (PC) register. Furthermore, while within fault handler, incorrectly points beginning fault record. This case happens when: local fault handler selected fault current execution mode Supervisor when fault occurs; current stack offset from quad-word boundary bytes: Where positive integer. other possible values generate erratum: Code Sequences Affected Assuming described above, erratum manifests itself time fault taken does result stack switch (all cases except system supervisor fault taken from user mode). This forces fault record become misaligned with respect stack pointer (SP) become non-quad-word aligned. fault type fault fields fault record then stored address FP+4 respectively. user cannot retrieve information from fault record location expected memory. Upon return from fault handler cleared. also cleared upon return fault handler executing supervisor mode. through
Implication: Workaround:
Requires extra code every fault handler extra time implement workaround. workaround requires special code beginning each fault handler that corrects unaligned fault record makes accessing fault record returning from fault handler operate correctly. There limitation workaround (discussed further detail below). workaround code guaranteed work versions 80960Jx present future. workaround consists assembly code that rewrites entire fault record aligned location when situation detected. This code should placed beginning fault handlers. RESTRICTION: application composed only code compiled Intel CTools compiler, then this anomaly cannot occur. application compiled another compiler contains customer routines coded directly 80960 assembly code, then possible improper fault record generated when fault occurs. code generated latter method, code restriction should followed ensure that improper fault record generated: always quadword aligned (i.e., always incremented decremented multiples 16), then proposed workaround needed.

Problem:
Software Interrupt Erratum
When processor executing supervisor mode process priority fault interrupt that comes from user mode lower process priority, software interrupt posted priority where Then fault interrupt return user mode executed. When restored return user mode process priority reset where U<S. result, before first instruction user mode execute, control transferred software interrupt handling mechanism interrupt posted priority error occurs when software interrupt handling mechanism updates interrupt table Software-Interrupt Priority Register before switching Supervisor mode. Because processor wrong mode, type.mismatch fault will occur control will transferred fault handling mechanism before first instruction software interrupt handler issued. Upon return from fault handler, execution interrupt handler will continue; however, subsequent software interrupts lost.
Implication: Workaround: Status:
Overhead needed make sure software interrupts occur user mode, loss software interrupt capabilities will result. only workarounds this erratum either allowing software interrupts while processor user mode avoiding software interrupts altogether. Fixed. Refer Summary Table Changes determine affected stepping(s).
Problem:
Pullup LOCK#/ONCE# Does Turn
LOCK#/ONCE# signals provided with weak pullup device intended keep processor from accidentally entering ONCE mode reset. pullup device supposed turn after deassertion RESET#. However, pullup remains even ONCE high impedance mode. strength pullup device measured which means looks approximately like resistor attached VCC.
Implication: Workaround:

Problem:
Cycle Performance Instruction Order with LOAD Instructions
Under certain conditions, LOAD instruction immediately followed instruction could cause extra cycle added execution time. This internal processor availability non-predictable. Instructions need re-ordered avoid performance loss. critical code sequences that contain LOAD's followed instruction, experiment with order instructions that follow LOAD instruction. This eliminate extra cycle. There workaround this problem. Fixed. Refer Summary Table Changes determine affected stepping(s).

Instructions Executed Between Back-to-Back Interrupts
processor insert instructions from interrupted process code between back-to-back interrupts under certain conditions. This situation could cause slightly longer interrupt latency depending instruction(s) executed. This situation occurs when processor executing interrupt handler, interrupt(s) pending priority which lower than current interrupt handler priority higher than interrupted process priority. Upon return from current interrupt handler, processor retains interrupt handler process priority cycles. This prevents lower priority interrupts from

Typically, targ register holds address branch specified user, register automatically loaded processor with address return When same register used targ, targ register, after being used calculate target address, receives processor-loaded address return Architecturally, using same registers targ permissible works other 80960 family members, 80960Jx this causes balx become non-functional. following example, balx should compute target address "xyz", load "abc" into r12, branch "xyz". However, "abc" gets loaded into processor branches "abc".

VCC(I/O) pins appear only 132-lead PQFP package. Pragmatically, this problem only occurs when VCCPLL, VCC(I/O), pins driven separate power supplies voltage regulators. Applications that power supply VCCPLL, VCC(I/O), typically risk. Verify that your application does allow VCCPLL voltage exceed diodes connect VCCPLL VCC(I/O) circuitry VCC. Normally, those diodes unbiased reverse-biased, current flows. event positive electrostatic pulse VCCPLL VCC(I/O), diodes protect phase-locked loop input/output circuitry shunting excess charge VCC.
