4.12 Block Locking by the WP#
This Boot Block Flash memory architecture features two
hardware-lockable boot blocks so that the kernel code for
the system can be kept secure while other blocks are
programmed or erased as necessary.
The lockable two boot blocks are locked when WP#=V
IL
;
any program or erase operation to a locked block will
result in an error, which will be reflected in the status
register. For top configuration, the top two boot blocks are
lockable. For the bottom configuration, the bottom two
boot blocks are lockable. If WP# is V
IH
and block lock-
bit is not set, boot block can be programmed or erased
normally (Unless V
CCW
is below V
CCWLK
). WP# is valid
only two boot blocks, other blocks are not affected.
