CP
CCPMX DEBUG
CP: Flash Program Memory Code Protection bits
1 = Code protection off
0 = 0000h to 1FFFh code-protected for PIC16F767/777 and 0000h to 0FFFh for PIC16F737/747 (all protected)
CCPMX: CCP2 Multiplex bit
1 = CCP2 is on RC1
0 = CCP2 is on RB3
DEBUG: In-Circuit Debugger Mode bit
1 = In-Circuit Debugger disabled, RB6 and RB7 are general purpose I/O pins
0 = In-Circuit Debugger enabled, RB6 and RB7 are dedicated to the debugger
BORV<1:0>: Brown-out Reset Voltage bits
11 = V
10 = V
01 = V
00 = V
BOREN: Brown-out Reset Enable bit
BOREN combines with BORSEN to control when BOR is enabled and how it is controlled.
BOREN:BORSEN:
11 = BOR enabled and always on
10 = BOR enabled during operation and disabled during Sleep by hardware
01 = BOR controlled by software bit SBOREN – refer to Register 2-8 (PCON<2>)
00 = BOR disabled
MCLRE: MCLR/V
1 = MCLR/V
0 = MCLR/V
PWRTEN: Power-up Timer Enable bit
1 = PWRT disabled
0 = PWRT enabled
WDTEN: Watchdog Timer Enable bit
1 = WDT enabled
0 = WDT disabled
111 = EXTRC oscillator; CLKO function on OSC2/CLKO/RA6
110 = EXTRC oscillator; port I/O function on OSC2/CLKO/RA6
101 = INTRC oscillator; CLKO function on OSC2/CLKO/RA6 and port I/O function on OSC1/CLKI/RA7
100 = INTRC oscillator; port I/O function on OSC1/CLKI/RA7 and OSC2/CLKO/RA6
011 = EXTCLK; port I/O function on OSC2/CLKO/RA6
010 = HS oscillator
001 = XT oscillator
000 = LP oscillator
