Notes:
1. tPCI_SYNC_IN is the clock period of the input clock applied to PCI_SYNC_IN. When the MPC8323E is In PCI host mode the
primary clock is applied to the CLKIN input, and PCI_SYNC_IN period depends on the value of CFG_CLKIN_DIV. See the
MPC8323E PowerQUICC II Pro Integrated Communications Processor Reference Manual for more details.
2. tCLKIN is the clock period of the input clock applied to CLKIN. It is only valid when the MPC8323E is in PCI host mode. See
the
MPC8323E PowerQUICC II Pro Integrated Communications Processor Reference Manual for more details.
3. POR configuration signals consists of CFG_RESET_SOURCE[0:2] and CFG_CLKIN_DIV.
