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