Timers inputs—minimum pulse width

tTIWID

Note:

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

Table 60. GPIO DC Electrical Characteristics

This specification applies when operating at 3.3 V ± 165 mV supply.
