Legend:
R = Readable bit WO = Write-Once bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 7-4 Unimplemented: Program the corresponding Flash Configuration bit to ‘1’
bit 3-2 Unimplemented: Read as ‘0’
bit 1 WPEND: Write-Protect Disable bit
1 = Flash pages, WPFP<6:0> through the Configuration Words page, are erase/write-protected
0 = Flash pages, 0 through WPFP<6:0>, are erase/write-protected
bit 0 WPDIS: Write-Protect Disable bit
1 = WPFP<6:0>/WPEND region is ignored
0 = WPFP<6:0>/WPEND region is erase/write-protected
