bit 7 bit 0
Legend:
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 7-3 Unimplemented: Read as ‘0’
bit 2 ETHLED: Ethernet LED Enable bit
1 = RA0/RA1 are multiplexed with LEDA/LEDB when the Ethernet module is enabled and function as
I/O when the Ethernet is disabled
0 = RA0/RA1 function as I/O regardless of Ethernet module status
bit 1 ECCPMX: ECCP MUX bit
(2)
1 = ECCP1 outputs (P1B/P1C) are multiplexed with RE6 and RE5;
ECCP3 outputs (P3B/P3C) are multiplexed with RE4 and RE3
0 = ECCP1 outputs (P1B/P1C) are multiplexed with RH7 and RH6;
ECCP3 outputs (P3B/P3C) are multiplexed with RH5 and RH4
bit 0 CCP2MX: ECCP2 MUX bit
(2)
1 = ECCP2/P2A is multiplexed with RC1
0 = ECCP2/P2A is multiplexed with RE7 in Microcontroller mode (80-pin and 100-pin devices)
or with RB3 in Extended Microcontroller mode (100-pin devices only)
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.
2: Implemented in 80-pin and 100-pin devices only.
