RX23W Group 24. Port Output Enable 2 (POE2a)
When low-level sampling has been set by the POE0M[1:0], POE1M[1:0], and POE3M[1:0] bits, writing 0 to the POE0F,
POE1F, and POE3F flags requires high-level input on the POE0#, POE1F, and POE3# pins.
For details, refer to
section 24.3.6, Release from the High-Impedance.
PIE1 Bit (Port Interrupt Enable 1)
This bit enables or disables OEI1 interrupt requests when any one of the POE0F, POE1F, and POE3F flags is set to 1.

POE3F Flag (POE3 Flag)
This flag indicates that a high-impedance request has been input to the POE3# pin.
[Setting condition]
When the input set by POE3M[1:0] occurs at the POE3# pin
[Clearing condition]
By writing 0 to POE3F after reading POE3F = 1
