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 program memory 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 program memory 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 program memory write protection is disabled
0 = Segmented program memory write 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
Reserved: Always maintain as ‘1’
WDTWIN<1:0>: Watchdog Timer Window Width Select bits
11 = 25%
10 = 37.5%
01 = 50%
00 = 75%
SOSCSEL: SOSC Selection bit
1 = SOSC circuit is selected
0 = Digital (SCLKI) mode⁽²⁾
Reserved: Always maintain as ‘1’
Note 1:
2:
3:
Regardless of WPCFG status, if WPEND = 1 or if WPFP<6:0> bits correspond 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 64K devices (PIC24FJ64GC0XX), maintain WPFP6 as ‘0’.
