Legend:
R = Readable bit
R = Readable bit
WO = Write-Once bit
U = Unimplemented bit, read as ‘0’
-n = Value when device is unprogrammed
‘1’ = Bit is set
‘0’ = Bit is cleared
bit 7-1
Unimplemented: Read as ‘0’
bit 0
CCP2MX: CCP2 MUX bit
1 = CCP2 is multiplexed with RC1
0 = CCP2 is multiplexed with RE7
1 = CCP2 is multiplexed with RC1
0 = CCP2 is multiplexed with RE7
Note 1:
The value of these bits in program memory should always be ‘1’. This ensures that the location is
executed as a NOP if it is accidentally executed.

Note 1:
The values for DEV<10:3> may be shared with other device families. The specific device is always
identified by using the entire DEV<10:0> bit sequence.
