Multiplexed signals shown default signal with secondary signal square brackets (for example, GPIO1[TS1E]). Active-low signals (for example, RAS) marked with overline. expected that single application particular will always programmed serve same function. flexibility multiplexing allows single chip offer richer selection than would otherwise possible. addition multiplexing, many pins also multi-purpose. example, peripheral controller address pins used outputs PPC405GPr broadcast address external slave devices when PPC405GPr control external bus. When, during course normal chip operation, external master gains ownership external bus, these same pins used inputs which driven external master received PPC405GPr. this example, pins also bidirectional, serving both inputs outputs. Intialization Strapping group pins used strapped inputs during system reset. These pins function strapped inputs only during reset used other functions during normal operation (see "Strapping" page 52). Note that these pins strapping considered multiplexing since strapping function programmable.

Spread Spectrum Clocking
Care must taken when using spread spectrum clock generator (SSCG) with PPC405GPr. This controller uses clock generation inside chip. accuracy with which follows SSCG referred tracking skew. bandwidth phase angle determine much tracking skew there between SSCG given frequency deviation modulation frequency. When using SSCG with PPC405GPr following conditions must met: frequency deviation must violate minimum clock cycle time. Therefore, when operating PPC405GPr with more internal clocks their maximum supported frequency, SSCG only lower frequency. maximum frequency deviation cannot exceed -3%, modulation frequency cannot exceed 40kHz. some cases, on-board PPC405GPr peripherals impose more stringent requirements (see Note peripheral clock (PerClk) logic that synchronous peripheral since this clock tracks modulation. SDRAM MemClkOut since also tracks modulation. Notes: serial port baud rates synchronous modulated clock. serial port tolerance approximately 1.5% baud rate before framing errors begin occur. 1.5% tolerance assumes that connected device running precise baud rates. external serial clock used baud rate unaffected modulation. Operation PPC405GPr Bridge unaffected SSCG. frequencies 33.33 below controller supports synchronous mode operation. This accomplished strapping PPC405GPr synchronous mode connecting clock PPC405GPr SysClk input. 33.33 signalling, specification limitation amount frequency deviation modulation that applied clock. Therefore, PPC405GPr SSCG requirements stated above take precedence. frequencies above 33.33 MHz, controller must operated asynchronous mode. When asynchronous mode, clock must driven into PPC405GPr PCIClk input. this configuration controller supports 66.66 clock specification which specifies maximum frequency deviation modulation between kHz. Ethernet operation unaffected. operation unaffected. Caution: system designer ensure that SSCG used with PPC405GPr meets above requirements does adversely affect other aspects system.

Strapping
When SysReset input driven external device (system reset), state certain pins read enable default initial conditions prior PPC405GPr start-up. actual capture instant nearest SysClk edge before deassertion reset. These pins must strapped using external pull-up (logical pull-down (logical resistors select desired default conditions. recommended pull-up +3.3V +5V. recommended pull-down GND. These pins strap functions only during reset. They used other signals during normal operation. following tables list strapping pins along with their functions strapping options. signal names assigned pins normal operation follow number. PPC405GPr used replacement PPC405GP. When PPC405GPr used this purpose, should strapped operate PPC405GPr Legacy Mode. This option selected strapping ball (GPIO24) (0). Legacy Mode selected, "PPC405GPr Legacy Mode Strapping Assignments" table should used determine strapping options. operate chip PPC405GPr, strap (GPIO24) high "PPC405GPr Mode Strapping Assignments" page determine strapping options.
