ICSR2 is a 16-bit readable/writable register that selects the POE4 to POE6 pin input modes,
controls the enable/disable of interrupts, and indicates status.

Writing 0 to this bit after reading it as 1 clears the flag and is the only allowed way.
Can be modified only once after a power-on reset.

Description
Reserved
This bit is always read as 0. The write value should
always be 0.
POE6 Flag
This flag indicates that a high impedance request has
been input to the POE6 pin.

By writing 0 to POE6F after reading POE6F = 1
(when the falling edge is selected by bits 5 and 4 in
ICSR2)
By writing 0 to POE6F after reading POE6F = 1 after
a high level input to POE6 is sampled at Pφ/8, Pφ/16,
or Pφ/128 clock (when low-level sampling is selected
by bits 5 and 4 in ICSR2)
When the input condition set by bits 5 and 4 in ICSR2
occurs at the POE6 pin
