18 GPIO
This section describes the DC and AC electrical specifications for the GPIO of the MPC8314E.
18.1
GPIO DC Electrical Characteristics
This table provides the DC electrical characteristics for the GPIO.
18.2
GPIO AC Timing Specifications
This table provides the GPIO input and output AC timing specifications.
Note:
1. Timers inputs and outputs are asynchronous to any visible clock. Timers outputs should be synchronized before use by any
external synchronous logic. Timers input are required to be valid for at least tTIWID ns to ensure proper operation.
