4.15 MPC8572 System Clock

An oscillator drives the MPC8572 system clock. The following table details the clock
frequencies for various processor configurations.

4.16 Reset Control Logic

There are multiple sources of reset on the CPCI-6200. The following table shows the reset
sources and their effect on board reset. The effect of each reset source depends on the board's
current status such as LRO switch setting, board in system or peripheral slot, Watchdog Control
Register value (WD_EN and SYS_RST), System Control Register value (SW_RST), CPCI Control
and Status Register value (BP_RST_MASK), etc.
