Legend:
R = Readable bit
-n = Value at POR
WO = Write-Once bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
x = Bit is unknown
bit 7-4
bit 3-1
bit 0
Unimplemented: Program the corresponding Flash Configuration bit to ‘1’
Unimplemented: Read as ‘0’
WPDIS: Write-Protect Disable bit
1 = WPFP<5:0> and WPEND bits are ignored; the specified region is not erase/write-protected
0 = WPFP<5:0> and WPEND bits are enabled; erase/write-protect is active for the selected region

DEV<2:0>: Device ID bits
These bits are used with the DEV<10:3> bits in Device ID Register 2 to identify the part number. See
Register 27-10.
REV<4:0>: Revision ID bits
These bits are used to indicate the device revision.
