Although designed microcontroller evaluation board, this utility work other vendor's platforms. (However, functionality outside microcontroller evaluation board cannot guaranteed therefore supported.) There elements compatibility: MMSVIEW assumes that MMSA programmed begin page C0000h. starting location MMSA reset utility attempt maintain software compatibility with customer platforms this would probably cause customer's platform crash. this utility customer platform only customer-platform initialization programs MMSA page start C0000h.

"Operating Instructions" page 3-13 details change windows. recommended that test platform/evaluation system "cold" booted (using reset button) after MMSVIEW exits that microcontroller setup registers restored proper values before doing further work platform. This required only customer platforms, microcontroller evaluation board that ROMDOS, EMM386, other drivers installed that require MMS, memory regions that controlled MMS. Again, MMSVIEW makes attempt restore system initial state: reset system when finished. caution when selecting page use.

8042 Keyboard Controller
evaluation board uses non-static 8042 keyboard controller. What this means programmer that SysCLK stops being driven 8042 period time, controller must reset once SysCLK starts being driven again order 8042 function properly. microcontroller stops driving SysCLK time Speed disabled when Sleep, Suspend modes even Speed enabled these modes. side effect driving SysCLK 8042 from 8042 will active short period time. This active state latched microcontroller. Therefore when microcontroller goes back High Speed mode from Sleep, Suspend mode, reset. Note that above conditions only apply non-static 8042. static 8042 used, then these conditions don't apply. work around these situations, evaluation board been wired pins microcontroller gate from 8042 (PMC4) reset 8042 (PMC0). PMC4 should programmed mask from 8042 while Sleep, Suspend, modes prevent from being reset SysCLK being driven Speed disabled Doze mode then PMC4 should driven this mode well.) When system goes back High Speed mode, 8042 needs reset pulsing PMC0 high millisecond. Commands should also issued 8042 re-enable keyboard. "PMC0" page "PMC4" page more information.

Appendix Board Layout Suggestions
following suggestions concern microcontroller evaluation board layout strategy 32-kHz oscillator, PLLs, power supplies. goal minimize noise noise coupling associated with board laid out. Special care needed minimize board leakages which fatal pins that sensitive leakage currents, such crystal oscillator pins, XTAl1 XTAL2.
32-kHz Oscillator
Prudent board layout 32-kHz oscillator suggests following precautions: Keep traces, XTAL1 XTAL2, short possible, especially input trace, XTAL1. XTAL1 extremely sensitive leakage. Total leakage from/to XTAL1 to/from pins board must kept under XTAL2 tolerate leakage high
Keep noisy signals (e.g., outputs other clocking signals) away from XTAL1 XTAL2 possible. Again, XTAL1 much more sensitive noise coupling than XTAL2. Minimize parasitic capacitance between XTAL1 XTAL2; even picofarads potentially cause oscillation frequency target. feedback resistor larger than fail start leakage XTAL1 equivalent less. feedback resistor value lowered counter leakage XTAL1, that increases start-up time. lower bound feedback resistor should about capacitors connected between XTAL1, XTAL2, analog ground should between they should about equal value. Increasing capacitor values increases start-up time power consumption, does reduce noise coupling into XTAL1 XTAL2.
Microcontroller Evaluation Board User's Manual
Phase-Locked Loops
Board layout considerations four PLLs suggest following precautions: Keep output traces four PLLs short possible keep them away from each other (and other clocking signals) possible. exceed specified loading four outputs. Certainly loading allowed since they CMOS logic outputs. PLLs have drive more load than they designed actual application, make sure they properly buffered board.
Power Supplies
Board layout considerations power supplies suggest following precautions: Bring analog digital separate traces from output voltage regulator microcontroller; making sure traces thick wide. Filter analog with second-order low-pass filter (e.g., L=47 C=33 µF). Since digital carries much more current than analog VCC, second order low-pass filter should used instead (i.e., series resistor should removed). small capacitor order nanofarads added parallel large filter capacitor suppress high-frequency noise. Isolate analog ground plane from digital ground plane board, connect them after decoupling.
