0000 = 1:2 (2.1 ms)
DSWDTEN
CONFIG3L
Deep Sleep Watchdog Timer Enable bit
1 = DSWDT enabled
0 = DSWDT disabled
DSBOREN
CONFIG3L
Deep Sleep BOR Enable bit
1 = BOR enabled in Deep Sleep
0 = BOR disabled in Deep Sleep (does not affect operation in non Deep Sleep modes)
RTCOSC
CONFIG3L
RTCC Reference Clock Select bit
1 = RTCC uses T1OSC/T1CKI as reference clock
0 = RTCC uses INTRC as reference clock
DSWDTOSC
CONFIG3L
DSWDT Reference Clock Select bit
1 = DSWDT uses INTRC as reference clock
0 = DSWDT uses T1OSC/T1CKI as reference clock
CONFIG3H
MSSP 7-Bit Address Masking Mode Enable bit
1 = 7-Bit Address Masking mode enable
0 = 5-Bit Address Masking mode enable
IOL1WAY
CONFIG3H
IOLOCK Bit One-Way Set Enable bit
1 = The IOLOCK bit (PPSCON<0>) can be set once, provided the unlock sequence has
been completed. Once set, the Peripheral Pin Select registers cannot be written to a
second time.
0 = The IOLOCK bit (PPSCON<0>) can be set and cleared as needed, provided the
unlock sequence has been completed
WPCFG(4)
CONFIG4L
Write/Erase Protect Configuration Words Page bit (valid when WPDIS = 0)
1 = Configuration Words page is not erase/write-protected unless WPEND and
WPFP<5:0> settings include the Configuration Words page
0 = Configuration Words page is erase/write-protected, regardless of WPEND and
WPFP<5:0> settings
WPEND
CONFIG4L
Write/Erase Protect Region Select bit (valid when WPDIS = 0)
1 = Flash pages, WPFP<5:0> to Configuration Words page, are write/erase-protected
0 = Flash pages, 0 to WPFP<5:0> are write/erase-protected
TABLE 5-5:
PIC18F46J11 AND PIC18F46J50 FAMILY DEVICES: BIT DESCRIPTIONS (CONTINUED)
Bit Name
Configuration
Words
Description
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 PIC18F46J11 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.
