WAIT: External Bus Data Wait Enable bit
1 = Wait selections unavailable, device will not wait
0 = Wait programmed by WAIT1 and WAIT0 bits of MEMCOM register (MEMCOM<5:4>)
Unimplemented: Read as ‘0’
PM1:PM0: Processor Data Memory Mode Select bits
11 = Microcontroller mode
10 = Microprocessor mode⁽¹⁾
01 = Microcontroller with Boot Block mode⁽¹⁾
00 = Extended Microcontroller mode⁽¹⁾
Note 1: This mode is available only on PIC18F8525/8621 devices.
Legend:
R = Readable bit
-n = Value after erase
P = Programmable bit U = Unimplemented bit, read as ‘0’
‘1’ = Bit is set
‘0’ = Bit is cleared x = Bit is unknown
