ICSR1 is a 16-bit readable/writable register that selects the POE0 to POE3 pin input modes,
controls the enable/disable of interrupts, and indicates status.

Description
POE3 Flag
Indicates that a high impedance request has been input
to the POE3 pin.
[Clearing conditions]

[Setting condition]
•
By writing 0 to POE3F after reading POE3F = 1
(when the falling edge is selected by bits 7 and 6 in
ICSR1)
By writing 0 to POE3F after reading POE3F = 1 after
a high level input to POE3 is sampled at Pφ/8, Pφ/16,
or Pφ/128 clock (when low-level sampling is selected
by bits 7 and 6 in ICSR1)
When the input set by bits 7 and 6 in ICSR1 occurs at
the POE3 pin
