Description
POE8 High-Impedance Enable
This bit specifies whether to place the pins in the high-
impedance state when the POE8F bit in ICSR3 is set
to 1.
0: Does not place the pins in the high-impedance state
1: Places the pins in the high-impedance state
Port Interrupt Enable 3
This bit enables or disables interrupt requests when the
POE8 bit in ICSR3 is set to 1.
0: Interrupt requests disabled
1: Interrupt requests enabled
Reserved
These bits are always read as 0. The write value should
always be 0.
POE8 mode 1 and 0
These bits select the input mode of the POE8 pin.
00: Accept request on falling edge of POE8 input
01: Accept request when POE8 input has been sampled
10: Accept request when POE8 input has been sampled
11: Accept request when POE8 input has been sampled
