WAIT: External Bus Data Wait Enable bit
1 = Wait selections unavailable for table reads and table writes
0 = Wait selections for table reads and table writes are determined by the WAIT1:WAIT0 bits
(MEMCOM<5:4>)
Unimplemented: Read as ‘0’
PM1:PM0: Processor Mode Select bits
11 = Microcontroller mode
10 = Microprocessor mode
01 = Microprocessor with Boot Block mode
00 = Extended Microcontroller mode
Note 1: This register is unimplemented in PIC18F6X20 devices; maintain these bits set.
Legend:
R = Readable bit
P = Programmable bit
- n = Value when device is unprogrammed
U = Unimplemented bit, read as ‘0’
u = Unchanged from programmed state

CCP2MX: CCP2 Mux bit
In Microcontroller mode:
1 = CCP2 input/output is multiplexed with RC1
0 = CCP2 input/output is multiplexed with RE7
In Microprocessor, Microprocessor with Boot Block and Extended Microcontroller modes
(PIC18F8X20 devices only):
1 = CCP2 input/output is multiplexed with RC1
0 = CCP2 input/output is multiplexed with RB3
Note 1: Unimplemented in PIC18FX620 and PIC18FX720 devices; read as ‘0’.
