RESERVED. Read = 0b. Must write 0b.
UNUSED. Read = 0b. Write = don’t care.
CP0RIE: Comparator Rising-Edge Interrupt Enable.
0: Comparator rising-edge interrupt disabled.
1: Comparator rising-edge interrupt enabled.
CP0FIE: Comparator Falling-Edge Interrupt Enable.
0: Comparator falling-edge interrupt disabled.
1: Comparator falling-edge interrupt enabled.
Note: It is necessary to enable both CP0xIE and the correspondent ECPx bit located in EIE1
SFR.
These bits select the response time for Comparator0.
Note: Rising Edge response times are approximately double the Falling Edge response
times.
