The following section summarizes the sampling window width for input signals for various input qualifier configurations.
Sampling frequency denotes how often a signal is sampled with respect to SYSCLK.
In the previous equations, SYSCLK cycle indicates the time period of SYSCLK.
Sampling period = SYSCLK cycle, if QUALPRD = 0
In a given sampling window, either 3 or 6 samples of the input signal are taken to determine the validity of the signal. This is determined by the value written to GPxQSELn register.
Case 1:
Qualification using 3 samples
Case 2:
Qualification using 6 samples
