4.3.16
The MPC5125 contains several sets of I/Os that do not require special setup, hold, or valid requirements. The external events
(GPIO or timer inputs) are asynchronous to the system clock. The inputs must be valid for at least t
capture by the internal IP clock.

T is the IP bus clock cycle. T = 15 ns is the minimum value (for the maximum IP bus frequency of 66 MHz).
The program length is defined by the value defined in the EPM_PGM_LENGTH bits of the IIM module.
