CAUTION:
PROTECT[7:0] — Block Protect Field
The read-always PROTECT[7:0] field protects array blocks from
program and erase operations. If LOCKCTL = 1 or SES = 1, writing to
PROTECT[7:0] has no effect.
Array blocks that correspond to 1s in PROTECT[7:0] are selected for
data address space.
Each array block can be protected from program and erase operation
by setting its PROTECT bit. The CMFR BIU performs all programming
and erase interlocks except that the program and erase voltages are
not applied to locations within the protected array block(s).
The default reset state of PROTECT[7:0] bits are protected
(PROTECT[M] = 1).
1 = Array block protected
0 = Array block not protected
If the LOCKCTL bit is set before PROTECT[7:0] is cleared, the device
must use debug mode to program or erase the CMFR.
