These bits are always read as 0. The write value should
always be 0.
By writing 0 to POE5F after reading POE5F = 1
(when the falling edge is selected by bits 3 and 2 in
ICSR2)
By writing 0 to POE5F after reading POE5F = 1 after
a high level input to POE5 is sampled at Pφ/8, Pφ/16,
or Pφ/128 clock (when low-level sampling is selected
by bits 3 and 2 in ICSR2)
When the input condition set by bits 3 and 2 in ICSR2
occurs at the POE5 pin
By writing 0 to POE4F after reading POE4F = 1
(when the falling edge is selected by bits 1 and 0 in
ICSR2)
By writing 0 to POE4F after reading POE4F = 1 after
a high level input to POE4 is sampled at Pφ/8, Pφ/16,
or Pφ/128 clock (when low-level sampling is selected
by bits 1 and 0 in ICSR2)
When the input condition set by bits 1 and 0 in ICSR2
occurs at the POE4 pin
