Legend:
R = Readable bit
-n = Value at POR
PO = Program Once bit
W = Writable bit
‘1’ = Bit is set
r = Reserved bit
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
x = Bit is unknown

Unimplemented: Read as ‘1’
WPEND: Segment Write Protection End Page Select bit
1 = Protected code segment upper boundary is at the last page of program memory; the lower
boundary is the code page specified by WPFP<6:0>
0 = Protected code segment lower boundary is at the bottom of the program memory (000000h); upper
boundary is the code page specified by WPFP<6:0>
WPCFG: Configuration Word Code Page Write Protection Select bit
1 = Last page (at the top of program memory) and Flash Configuration Words are not write-protected⁽¹⁾
0 = Last page and Flash Configuration Words are write-protected provided WPDIS = ‘0’
WPDIS: Segment Write Protection Disable bit
1 = Segmented code protection is disabled
0 = Segmented code protection is enabled; protected segment is defined by the WPEND, WPCFG and
WPFPx Configuration bits
BOREN: Brown-out Reset Enable bit
1 = BOR is enabled (all modes except Deep Sleep)
0 = BOR is disabled
WDTWIN<1:0>: Watchdog Timer Window Width Select bits
11 = 25%
10 = 37.5%
01 = 50%
00 = 75%
Reserved: Always maintain as ‘1’
SOSCSEL: SOSC Selection bit
1 = SOSC circuit is selected
0 = Digital (SCLKI) mode⁽²⁾
VBTBOR: VBAT BOR Enable bit
1 = VBAT BOR is enabled
0 = VBAT BOR is disabled
Note 1:
2:
3:
Regardless of WPCFG status, if WPEND = 1 or if WPFP corresponds to the Configuration Word page, the
Configuration Word page is protected.
Ensure that the SCLKI pin is made a digital input while using this configuration (see Table 11-1).
For the 62K devices: PIC24FJ64GA310, PIC24FJ64GA308 and PIC24FJ64GA306, bit 6 should be
maintained as ‘0’.
