TABLE 5-7:
PIC18F47J13 AND PIC18F47J53 FAMILY DEVICES: BIT DESCRIPTIONS
Bit Name
Configuration
Words
Description
DEBUG
CONFIG1L
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
CONFIG1L
Enhanced 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
CONFIG1L
Stack Overflow/Underflow Reset Enable bit
1 = Reset on stack overflow/underflow enabled
0 = Reset on stack overflow/underflow disabled
CFGPLLEN
CONFIG1L
Enable PLL on Start-up bit
1 = PLL enabled on start-up. Not recommended for low-voltage designs.
0 = PLL disabled on start-up. Firmware may later enable PLL through OSCTUNE<6>.
PLLDIV<2:0>
CONFIG1L
96 MHz PLL Input Divider bits
Divider must be selected to provide a 4 MHz input into the 96 MHz PLL.
111 = No divide – oscillator used directly (4 MHz input)
110 = Oscillator divided by 2 (8 MHz input)
101 = Oscillator divided by 3 (12 MHz input)
100 = Oscillator divided by 4 (16 MHz input)
011 = Oscillator divided by 5 (20 MHz input)
010 = Oscillator divided by 6 (24 MHz input)
001 = Oscillator divided by 10 (40 MHz input)
000 = Oscillator divided by 12 (48 MHz input)
WDTEN
CONFIG1L
Watchdog Timer Enable bit
1 = WDT enabled
0 = WDT disabled (control is placed on SWDTEN bit)
CP0(4)
CONFIG1H
Code Protection bit
1 = Program memory is not code-protected
0 = Program memory is code-protected
CPDIV<1:0>(3)
CONFIG1H
CPU System Clock Selection bits
11 = No CPU system clock divide
10 = CPU system clock divided by 2
01 = CPU system clock divided by 3
00 = CPU system clock divided by 6
IESO
CONFIG2L(1,2)
Two-Speed Start-up (Internal/External Oscillator Switchover) Control bit
1 = Oscillator Switchover mode enabled
0 = Oscillator Switchover mode disabled
FCMEN
CONFIG2L(1,2)
Fail-Safe Clock Monitor Enable bit
1 = Fail-Safe Clock Monitor enabled
0 = Fail-Safe Clock Monitor disabled
CLKOEC
CONFIG2L
EC Mode Clock Output Enable bit
1 = CLKO output signal active on the RA6 pin (EC mode only)
0 = CLKO output disabled
SOSCSEL<1:0>
CONFIG2L
Secondary Oscillator Circuit Selection bits
11 = High-power SOSC circuit selected
10 = Digital Input mode (SCLKI)
01 = Low-power SOSC circuit selected
00 = Reserved
Note 1: The Configuration bits can only be programmed indirectly by programming the Flash Configuration Word.
2: The Configuration bits are reset to ‘1’ only on VDD Reset; it is reloaded with the programmed value at any device Reset.
3: These bits are not implemented in PIC18F47J13 family devices.
4: Once this bit is cleared, all the Configuration registers which reside in the last page are also protected. To disable code
protection, perform an ICSP Bulk Erase operation.
5: Not implemented on PIC18F47J53 family devices.
