Input Level Detection Operation: If the input conditions set by the ICSR1 occur on any of the
POE pins, all high-current pins become high-impedance state. However, only when the general
input/output function or MTU function is selected, the large-current pin is in the high-impedance
state.

When a change from high to low level is input to the POE pins.
Figure 10.115 shows the low-level detection operation. Sixteen continuous low levels are
sampled with the sampling clock established by the ICSR1. If even one high level is detected
during this interval, the low level is not accepted.
Furthermore, the timing when the large-current pins enter the high-impedance state from the
sampling clock is the same in both falling-edge detection and in low-level detection.
PE15/TIOC4D/IRQOUT) also go to the high-impedance state at the same timing.
