GPIO inputs—minimum pulse width
Notes:
1. Input specifications are measured from the 50 percent level of the signal to the 50 percent level of the rising edge of CLKIN.
Timings are measured at the pin.
2. GPIO inputs and outputs are asynchronous to any visible clock. GPIO outputs should be synchronized before use by external
synchronous logic. GPIO inputs must be valid for at least t
