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).
Not available on 32K devices.
Not available on 32K and 16K devices.
Unimplemented: Program the corresponding Flash Configuration bit to ‘1’
MSSPMSK: MSSP 7-Bit Address Masking Mode Enable bit
1 = 7-Bit Address Masking mode enabled
0 = 5-Bit Address Masking mode enabled
Unimplemented: Read as ‘0’
IOL1WAY: IOLOCK One-Way Set Enable bit
1 = IOLOCK bit (PPSCON<0>) can be set once, provided the unlock sequence has been completed.
0 = IOLOCK bit (PPSCON<0>) can be set and cleared as needed, provided the unlock sequence has
WPCFG: Write/Erase Protect Configuration Region Select bit (valid when WPDIS = 0)
1 = Configuration Words page is not erase/write-protected, regardless of WPEND and WPFP<5:0>
0 = Configuration Words page is erase/write-protected, regardless of WPEND and WPFP<5:0>
WPEND: 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 erase/write-protected
WPFP<5:0>: Write/Erase Protect Page Start/End Location bits
Used with WPEND bit to define which pages in Flash will be erase/write-protected.
