Legend:
R = Readable bit
-n = Value at POR
r = Reserved bit
W = Writable bit
‘1’ = Bit is set
P = Programmable bit
U = Unimplemented bit, read as ‘0’
‘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 pro-
gramming 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 23-16 Reserved: Write ‘1’
Note 1: This bit sets the value for the JTAGEN bit in the CFGCON register.
2: The PGEC4/PGED4 pin pair is not available on all devices. Refer to the “Pin Diagrams” section for
availability.
