CCP2MX
bit 7
bit 0
Legend:
R = Readable bit
WO = Write-Once bit
-n = Value when device is unprogrammed
U = Unimplemented bit, read as ‘0’
‘1’ = Bit is set
‘0’ = Bit is cleared
bit 7-1
bit 0
Unimplemented: Read as ‘0’
CCP2MX: CCP2 MUX bit
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.

DEV<10:3>: Device ID bits(1)
These bits are used with the DEV<2:0> bits in the Device ID Register 1 to identify the part number.
0101 0000 = PIC18F87J90 family devices
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.
