These bits are always read as 0. The write value should
always be 0.
By writing 0 to POE1F after reading POE1F = 1
(when the falling edge is selected by bits 3 and 2 in
ICSR1)
By writing 0 to POE1F after reading POE1F = 1 after
a high level input to POE1 is sampled at Pφ/8, Pφ/16,
or Pφ/128 clock (when low-level sampling is selected
by bits 3 and 2 in ICSR1)
When the input set by ICSR1 bits 3 and 2 occurs at
the POE1 pin
By writing 0 to POE0F after reading POE0F = 1
(when the falling edge is selected by bits 1 and 0 in
ICSR1)
By writing 0 to POE0F after reading POE0F = 1 after
a high level input to POE0 is sampled at Pφ/8, Pφ/16,
or Pφ/128 clock (when low-level sampling is selected
by bits 1 and 0 in ICSR1)
When the input set by ICSR1 bits 1 and 0 occurs at
the POE0 pin
