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
BOR
set to 2.0V
10
= V
BOR
set to 2.7V
01
= V
BOR
set to 4.2V
00
= V
BOR
set to 4.5V
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
PP
/RE3 Pin Function Select bit
1
= MCLR/V
PP
/RE3 pin function is MCLR
0
= MCLR/V
PP
/RE3 pin function is digital input only, MCLR gated to ‘1’
PWRTEN:
Power-up Timer Enable bit
1
= PWRT disabled
0
= PWRT enabled
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
