Legend:
R = Readable bit
-n = Value at POR
WO = Write-Once bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
x = Bit is unknown
bit 7-4
bit 3
bit 2
bit 1
bit 0
Unimplemented: Program the corresponding Flash Configuration bit to ‘1’
MSSPMSK: MSSP 7-Bit Address Masking Mode Enable bit
1 = 7-Bit Address Masking mode is enabled
0 = 5-Bit Address Masking mode is enabled
Unimplemented: Read as ‘0’
ADCSEL: A/D Converter Mode
1 = 10-bit conversion mode is enabled
0 = 12-bit conversion mode is enabled
IOL1WAY: IOLOCK One-Way Set Enable bit
1 = 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 = IOLOCK bit (PPSCON<0>) can be set and cleared as needed, provided the unlock sequence has
been completed

WPCFG: Write/Erase Protect Configuration Region Select 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⁽¹⁾
0 = Configuration Words page is erase/write-protected, regardless of WPEND and WPFP<5:0>⁽¹⁾
WPFP<6:0>: Write/Erase Protect Page Start/End Location bits
Used with WPEND bit to define which pages in Flash will be write/erase protected.
Note 1: The “Configuration Words page” contains the FCWs and is the last page of implemented Flash memory on
a given device. Each page consists of 1,024 bytes. For example, on a device with 64 Kbytes of Flash, the
first page is 0 and the last page (Configuration Words page) is 63 (3Fh).
