Electrical and Thermal Characteristics
3.3.21
The MPC5121e/MPC5123 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 tIOWID to
ensure proper capture by the internal IP clock.

The program length is defined by the value defined in the EPM_PGM_LENGTH bits of the IIM module.
T is the IP bus clock cycle. T= 12 ns is the minimum value (for the maximum IP bus freqency of 83 MHz).
