Legend:
R = Readable bit W = Writable bit P = Programmable bit r = Reserved bit
U = Unimplemented bit ‘1’ = Bit is set ‘0’ = Bit is cleared 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.
