5.3.1 General Switching Specifications
These general purpose specifications apply to all signals configured for EGPIO, MTIM,
CMT, PDB, IRQ, and I
and full temperature range. The GPIO are set for high drive, no slew rate control, and no
input filter, digital or analog, unless otherwise specified.
1. The greater synchronous and asynchronous timing must be met.
2. This is the shortest pulse that is guaranteed to be recognized.
