RESET Initialization
Note that at MPX = 400 MHz, cfg_plat_freq = 0 and at MPX > 400 MHz, cfg_plat_freq = 1. Therefore,
when operating PCI Express in x8 link width, the MPX platform frequency must be 400 MHz with
cfg_plat_freq = 0 or greater than or equal to 527 MHz with cfg_plat_freq = 1.
For proper Serial RapidIO operation, the MPX clock frequency must be greater than:
4.5
For information on the input clocks of other functional blocks of the platform such as SerDes, and eTSEC,
see the specific section of this document.

This section describes the AC electrical specifications for the RESET initialization timing requirements of
the MPC8640.

Required assertion time of HRESET
Minimum assertion time for SRESET_0 & SRESET_1
Platform PLL input setup time with stable SYSCLK before HRESET
negation
Input setup time for POR configs (other than PLL config) with respect to
negation of HRESET
Input hold time for all POR configs (including PLL config) with respect to
negation of HRESET
Maximum valid-to-high impedance time for actively driven POR configs
with respect to negation of HRESET
Notes:
1. SYSCLK is the primary clock input for the MPC8640.
2 This is related to HRESET assertion time. Stable PLL configuration inputs are required when a stable SYSCLK is applied. See
(Platform and E600) PLL lock times
Local bus PLL
Notes:
1.The PLL lock time for e600 PLLs require an additional 255 MPX_CLK cycles.
