Block Locking
The B3 flash memory device architecture features two hardware-lockable parameter blocks.
WP# = V
The lockable blocks are locked when WP# = V
block results in an error, which is reflected in the Status Register:
Unlocked blocks can be programmed or erased normally (unless V
WP# = V
WP# = V
RP# does not override WP# locking for the B3 flash memory device, as in previous Boot Block
devices.

For top configuration, the top two parameter blocks are lockable:
For the bottom configuration, the bottom two parameter blocks are lockable. These are blocks
#0 and #1 for 4, 8 , 16, 32, and 64 Mbit.
WP# controls all block locking.
