Description
POE3 mode 1, 0
(Supported only by the SH7125. Write 00 to these bits in
the SH7124.)
These bits select the input mode of the POE3 pin.
10: Accept request when POE3 input has been sampled
11: Accept request when POE3 input has been sampled
Reserved
These bits are always read as 0. The write value should
always be 0.
POE1 mode 1, 0
These bits select the input mode of the POE1 pin.
10: Accept request when POE1 input has been sampled
11: Accept request when POE1 input has been sampled
Port Interrupt Enable 1
This bit enables/disables interrupt requests when any one
of the POE0F to POE3F bits of the ICSR1 is set to 1.
0: Interrupt requests disabled
1: Interrupt requests enabled
00: Accept request on falling edge of POE3 input
01: Accept request when POE3 input has been sampled
00: Accept request on falling edge of POE1 input
01: Accept request when POE1 input has been sampled
