• When the MCU is in watch mode or subactive mode, if the high level period before the falling edge of
INT
0 is shorter than the interrupt frame, INT0 is not detected. Also, if the low level period after the
falling edge of
INT
0 is shorter than the interrupt frame, INT0 is not detected.
Edge detection is shown in figure 19. The level of the
INT
0 signal is sampled by a sampling clock.
When this sampled value changes to low from high, a falling edge is detected.
In figure 20, 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 is not detected. In (b), the sampled
value is high at point A, and also high at point B. A falling edge is not 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 interrupt frame.
