Figure 3. EGPIO timing diagram
The following general purpose specifications apply to all signals configured for RGPIO,
FTM, and UART. The conditions are 25 pf load, VDD = 3.6 V to 1.71 V, 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.
