GPIO pins include: Ports A-I, INT, SPI, SCI1/2 (including SCI functions), FlexCAN and Timer.
Because of long delays associated with the PQA/PQB pads, signals on the PQA/PQB pins will be updated on the
following edge of the clock.

All AC timing is shown with respect to 50% V
During low-power STOP, the synchronizers for the RSTI input are bypassed and RSTI is asserted asynchronously to
the system. Thus, RSTI must be held a minimum of 100 ns.
RSTI Input valid to CLKOUT High
CLKOUT High to RSTI Input invalid
RSTI Input valid Time
CLKOUT High to RSTO Valid
RSTO valid to Config. Overrides valid
Configuration Override Setup Time to RSTO invalid
Configuration Override Hold Time after RSTO invalid
RSTO invalid to Configuration Override High Impedance
