Input Level Detection Operation: If the input conditions set by the ICSR1 occur on any of the 
POE0 to POE3 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. 

1. Falling Edge Detection: 

When a change from high to low level is input to the 

POE0 to POE3 pins, all high-current pins 

become high-impedance state. Figure 18.115 shows the timing example for the 

POE0 to POE3 

pins which enters the high-impedance state through input of a change from high to low level.

Note:   Other high-current pins (TIOC3D/PTE[4], TIOC4A/PTE[3], TIOC4B/PTE[2], TIOC4C/PTE[1], TIOC4D/PTE[0]) also
            become the Hi-Z state at the same timing.
