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.
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 t
