Description
Reserved
These bits are always read as 0. These bits should always
be written with 0
Port Interrupt Enable
This bit enables/disables interrupt requests when any of
the POE0F to POE3F bits of the ICSR1 are set to 1
0: Interrupt requests disabled
1: Interrupt requests enabled
POE3 mode 1, 0
These bits select the input mode of the POE3 pin
00: Accept request on falling edge of POE3 input
01: Accept request when POE3 input has been sampled
for 16 Pφ/8 clock pulses, and all are low level.
10: Accept request when POE3 input has been sampled
for 16 Pφ/16 clock pulses, and all are low level.
11: Accept request when POE3 input has been sampled
for 16 Pφ/128 clock pulses, and all are low level.
POE2 mode 1, 0
These bits select the input mode of the POE2 pin
00: Accept request on falling edge of POE2 input
01: Accept request when POE2 input has been sampled
for 16 Pφ/8 clock pulses, and all are low level.
10: Accept request when POE2 input has been sampled
for 16 Pφ/16 clock pulses, and all are low level.
11: Accept request when POE2 input has been sampled
for 16 Pφ/128 clock pulses, and all are low level.
POE1 mode 1, 0
These bits select the input mode of the POE1 pin
00: Accept request on falling edge of POE1 input
01: Accept request when POE1 input has been sampled
for 16 Pφ/8 clock pulses, and all are low level.
10: Accept request when POE1 input has been sampled
for 16 Pφ/16 clock pulses, and all are low level.
11: Accept request when POE1 input has been sampled
for 16 Pφ/128 clock pulses, and all are low level.
