When the PCI controller is configured for asynchronous operation, the reference clock for the PCI controller is not the SYSCLK
input, but instead the PCI_CLK.
At recommended operating conditions (see
2.4.3
The RTC input is sampled by the platform clock (CCB clock). The output of the sampling latch is then used as an input to the
counters of the PIC and the TimeBase unit of the e500. There is no jitter specification. The minimum pulse width of the RTC
signal should be greater than 2x the period of the CCB clock. That is, minimum clock high time is 2 × t
low time is 2 × t
