GPIO
This section describes the DC and AC electrical specifications for the GPIO interface of the MPC8536E.
2.18.1
GPIO DC Electrical Characteristics
Table 65 provides the DC electrical characteristics for the GPIO interface.
2.18.2
GPIO AC Electrical Specifications
Table 66 provides the GPIO input and output AC timing specifications.
Figure 53 provides the AC test load for the GPIO.

Notes:
1. Input specifications are measured from the 50% level of the signal to the 50% level of the rising edge of CLKIN. Timings
are measured at the pin.
2. GPIO inputs and outputs are asynchronous to any visible clock. GPIO outputs should be synchronized before use by any
external synchronous logic. GPIO inputs are required to be valid for at least tPIWID ns to ensure proper operation.
3. The minimum pulse width is a function of the MPX/Platform clock. The minimum pulse width must be greater than or equal
to 4 times the MPX/Platform clock period.
