In figure 24, the level of the
INT
0
signal is sampled by an interrupt frame. In (a) the sampled value is
low at point A, and also low at point B. Therefore, a falling edge will not be detected. In (b), the
sampled value is high at point A, and also high at point B. A falling edge will not be detected in this
case either.
When the MCU is in watch mode or subactive mode, keep the high level and low level period of
INT
0
longer than the interrupt frame.
