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.Timers inputs and outputs are asynchronous to any visible clock. Timers outputs should be synchronized before use
by any external synchronous logic. Timers inputs are required to be valid for at least tTIWID ns to ensure proper
operation.
