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
For the 62K devices: PIC24FJ64GA310, PIC24FJ64GA308 and PIC24FJ64GA306, bit 6 should be
maintained as ‘0’.
Unimplemented: Read as ‘1’

1 = Protected code segment upper boundary is at the last page of program memory; the lower
0 = Protected code segment lower boundary is at the bottom of the program memory (000000h); upper
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
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
BOREN: Brown-out Reset Enable bit
1 = BOR is enabled (all modes except Deep Sleep)
0 = BOR is disabled
