3.3.16 GPIOs and Timers
3.3.16.1 General and Asynchronous Signals
The MPC5200 contains several sets if I/Os that do not require special setup, hold, or valid requirements.
Most of these are asynchronous to the system clock. The following numbers are provided for test and
validation purposes only, and they assume a 133 MHz internal bus frequency.
Figure 46 shows the GPIO Timing Diagram. Table 50 gives the timing specifications.
