R = Readable bit
U = Unimplemented bit
W = Writable bit
P = Programmable bit
-n = Bit Value at POR: (‘0’, ‘1’, x = Unknown)
r = Reserved bit
bit 31-22
Reserved: Write ‘0’; ignore read
bit 21-0
CNEN<21:0>: CNEN Register bits
If a port pin is configured as an input (corresponding TRISx bit = 1)
1 = Port pin input change notice enabled
0 = Port pin input change notice disabled
If a port pin is configured as an output, CNENx bits have no effect
Note 1: Depending on the device, certain register bits or the entire register may not be implemented. Refer to
Table 12.1 for specific register and bit assignments.
