Notes:
1. Input specifications are measured from the 50% level of the signal to the 50% level of the rising edge of SYS_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 any
external synchronous logic. GPIO inputs are required to be valid for at least tPIWID ns to ensure proper operation.
