RESET Initialization
This section describes the AC electrical specifications for the RESET initialization timing requirements of
the MPC8641. Table 11 provides the RESET initialization AC timing specifications.
Table 12 provides the PLL lock times.

Notes:
1. SYSCLK is the primary clock input for the MPC8641.
2 This is related to HRESET assertion time. Stable PLL configuration inputs are required when a stable SYSCLK is
applied. See the
MPC8641D Integrated Host Processor Reference Manual for more details on the power-on reset
sequence.
