Legend: r = Reserved bit
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 31 Reserved: Write as ‘0’
bit 30-0 Reserved: Write as ‘1’
Note: The DEVSIGN1 through DEVSIGN3 and ADEVSIGN1 through ADEVSIGN3 registers are used for Quad
Word programming operation when programming the DEVSIGN0/ADESIGN0 registers, and do not contain
any valid information.

Legend: r = Reserved bit P = Programmable bit
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 31-29 Reserved: Write as ‘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 27-0 Reserved: Write as ‘1’
Note: The DEVCP1 through DEVCP3 and ADEVCP1 through ADEVCP3 registers are used for Quad Word
programming operation when programming the DEVCP0/ADEVCP0 registers, and do not contain any valid
information.
