0 = Fail-Safe Clock Monitor is disabled
IESO: Internal External Switchover bit
1 = Internal/External Switchover mode is enabled
0 = Internal/External Switchover mode is disabled
CLKOUTEN: Clock Out Enable bit
1 = CLKOUT function is disabled. I/O or oscillator function on RA6/CLKOUT
0 = CLKOUT function is enabled on RA6/CLKOUT
BOREN<1:0>: Brown-out Reset Enable bits
11 = BOR enabled
10 = BOR enabled during operation and disabled in Sleep
01 = BOR controlled by SBOREN bit of the PCON register
00 = BOR disabled
CPD: Data Code Protection bit
1 = Data memory code protection is disabled
0 = Data memory code protection is enabled
CP: Code Protection bit
1 = Program memory code protection is disabled
