Section 12 Port Output Enable 2 (POE2)
12.4.1
If the input conditions set by ICSR1 to ICSR3 occur on the POE0 to POE8 pins, the high-current
pins and the pins for channel 0 of the MTU2 are placed in high-impedance state. Note however,
that these high-current 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 POE8 pins, the high-current pins
and the pins for channel 0 of the MTU2 are placed in high-impedance state.
Figure 12.2 shows the sample timing after the level changes in input to the POE0 to POE8 pins
until the respective pins enter high-impedance state.
