General Purpose I/O Timing
GPIO can be configured for certain pins of the QSPI, DDR Control, timer, UART, Interrupt and USB interfaces. When in GPIO
mode, the timing specification for these pins is given in Table 21 and Figure 11.
The GPIO timing is met under the following load test conditions:
50 pF / 50
