Chapter 24 DG128 Port Integration Module (S12XDG128PIMV2)
A valid edge on an input is detected if 4 consecutive samples of a passive level are followed by
4 consecutive samples of an active level directly or indirectly.
The filters are continuously clocked by the bus clock in run and wait mode. In stop mode, the clock is
generated by an RC-oscillator in the port integration module. To maximize current saving the RC
oscillator runs only if the following condition is true on any pin individually:
Sample count <= 4 and interrupt enabled (PIE = 1) and interrupt flag not set (PIF = 0).
