RESET Initialization

This section describes the AC electrical specifications for the reset initialization timing requirements of

the MPC8323E. Table 9 provides the reset initialization AC timing specifications for the reset

component(s).

Table 10 provides the PLL lock times.

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.
