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 PPC405GP broadcast address external slave devices when PPC405GP 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 PPC405GP. 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 56). Note

Spread Spectrum Clocking
Care must taken when using spread spectrum clock generator (SSCG) with PPC405GP. 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 PPC405GP following conditions must met: frequency deviation must violate minimum clock cycle time. Therefore, when operating PPC405GP 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 PPC405GP 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. Please refer application note Using Spread Spectrum Clock Generator with PowerPC 405GP additional details. This application note available Microelectronics site http://www.chips.ibm.com. 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 PPC405GP Bridge unaffected SSCG. frequencies 33.33 below controller supports synchronous mode operation. This accomplished strapping PPC405GP synchronous mode connecting clock PPC405GP SysClk input. 33.33 signalling, specification limitation amount frequency deviation modulation that applied clock. Therefore, PPC405GP SSCG requirements stated above take precedence. frequencies above 33.33 MHz, controller must operated asynchronous mode. When asynchronous mode, clock must driven into PPC405GP 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 PPC405GP meets above requirements does adversely affect other aspects system.

Strapping

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 table lists strapping pins along with their functions strapping options. 456-ball package listed first (for example, AF3), followed corresponding 413-ball package (for example, U8), which appears AF3/U8. signal names assigned pins normal operation follow numbers.
