Notes:
1. The GPIO module can operate up to 108 MHz, however the maximum operating
frequency may be limited due to the wide variation of T
window is required for data out then the maximum recommended operating frequency is 50
MHz for T
2. Timing applies whether the data is output on a positive or negative edge. GPIO[6:0] can
be selected as clocks. Data can be any of the GPIO[60:0] as defined in
page
1-3.
