CP CCPMX DEBUG — — BORV1 BORV0 BOREN MCLRE FOSC2 PWRTEN WDTEN FOSC1 FOSC0
bit 13
bit 0
bit 13 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)
bit 12 CCPMX: CCP2 Multiplex bit
1 = CCP2 is on RC1
0 = CCP2 is on RB3
bit 11 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
bit 10-9 Unimplemented: Read as ‘1’
bit 8-7 BORV<1:0>: Brown-out Reset Voltage bits
11 = VBOR set to 2.0V
10 = VBOR set to 2.7V
01 = VBOR set to 4.2V
00 = VBOR set to 4.5V
bit 6 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
bit 5 MCLRE: MCLR/VPP/RE3 Pin Function Select bit
1 = MCLR/VPP/RE3 pin function is MCLR
0 = MCLR/VPP/RE3 pin function is digital input only, MCLR gated to ‘1’
bit 3 PWRTEN: Power-up Timer Enable bit
1 = PWRT disabled
0 = PWRT enabled
bit 2 WDTEN: Watchdog Timer Enable bit
1 = WDT enabled
0 = WDT disabled
bit 4, 1-0 FOSC2:FOSC0: Oscillator Selection bits
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
Legend:
R = Readable bit
-n = Value at POR
W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
x = Bit is unknown
