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

DEBUG: Background Debugger Enable bit
1 = Background debugger disabled; RB6 and RB7 configured as general purpose I/O pins
0 = Background debugger enabled; RB6 and RB7 are dedicated to In-Circuit Debug
XINST: Extended Instruction Set Enable bit
1 = Instruction set extension and Indexed Addressing mode enabled
0 = Instruction set extension and Indexed Addressing mode disabled (Legacy mode)
STVREN: Stack Overflow/Underflow Reset Enable bit
1 = Reset on stack overflow/underflow enabled
0 = Reset on stack overflow/underflow disabled
Unimplemented: Read as ‘0’
WDTEN: Watchdog Timer Enable bit
1 = WDT enabled
0 = WDT disabled (control is placed on SWDTEN bit)

bit 1-0
Unimplemented: Read as ‘1’(1)
Unimplemented: Read as ‘0’(2)
CP0: Code Protection bit
1 = Program memory is not code-protected
0 = Program memory is code-protected
Unimplemented: Read as ‘0’
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: This bit should always be maintained as ‘0’.
