Legend:
R = Readable bit
U = Unimplemented bit
W = Writable bit
‘1’ = Bit is set
P = Programmable bit
‘0’ = Bit is cleared
r = Reserved bit
x = Bit is unknown
bit 31 Reserved: Write ‘0’
bit 30-29 Reserved: Write ‘1’
bit 28 CP: Code-Protect bit
Prevents boot and program Flash memory from being read or modified by an external programming device.
1 = Protection is disabled
0 = Protection is enabled
bit 27-25 Reserved: Write ‘1’
bit 24 BWP: Boot Flash Write-Protect bit
Prevents boot Flash memory from being modified during code execution.
1 = Boot Flash is writable
0 = Boot Flash is not writable
bit 23-20 Reserved: Write ‘1’
bit 19-12 PWP<7:0>: Program Flash Write-Protect bits
Prevents selected program Flash memory pages from being modified during code execution. The PWP bits
represent the 1’s complement of the number of write-protected program Flash memory pages.
