12.4.1
If the input conditions set by ICSR1 to ICSR3 occur on the POE0 to POE2, POE4 to POE6, and
POE8 pins, the large current pins and the pins for channel 0 of the MTU2 are placed in the high-
impedance state. Note however, that these large current pins and MTU2 pins enter high-
impedance state only when general input/output function, MTU2 function, or MTU2S function is
selected for these pins.
(1)
When a change from a high to low level is input to the POE0 to POE2, POE4 to POE6, and POE8
pins, the large current pins and the pins for channel 0 of the MTU2 are placed in the high-
impedance state. Figure 12.2 shows a sample timing after the level changes in input to the POE0
to POE2, POE4 to POE6, and POE8 pins until the respective pins enter high-impedance state.
POE input
Note: * Other large current pins also enter the high-impedance state with the same timing.
