Notes:

1. Input specifications are measured from the 50% level of the signal to the 50% 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 any

external synchronous logic. GPIO inputs are required to be valid for at least tPIWID ns to ensure proper operation.

3. The minimum pulse width is a function of the MPX/platform clock. The minimum pulse width must be greater than or equal

to 4 times the MPX/platform clock period.
