Nonswitching electrical specifications
1. The greater synchronous and asynchronous timing must be met.
2. This is the shortest pulse that is guaranteed to be recognized.
The following general purpose specifications apply to all signals configured for RGPIO,
FTM, and UART. The conditions are 25 pf load, V
temperature range. The GPIO are set for high drive, no slew rate control, and no input
filter, digital or analog, unless otherwise specified.
