GPIOs and Timers
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 tIOWID to ensure proper
capture by the internal IP clock.
