The platform PLL generates the platform clock from the externally supplied SYSCLK input. The
frequency ratio between the platform and SYSCLK is selected using the platform PLL ratio
configuration bits as described in
The e500 core PLL generates the core clock as a slave to the platform clock. The frequency ratio
between the e500 core clock and the platform clock is selected using the e500 PLL ratio
configuration bits as described in
The PCI PLL generates the clocking for the PCI bus.
The local bus PLL generates the clock for the local bus.
There are two PLLs for the SerDes block.
