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 will result in an error, which will be reflected in the Status Register:
•
ESS
For top configuration, the top two parameter blocks (blocks #133 and #134 for the 64 Mbit,
#69 and #70 for the 32 Mbit, blocks #37 and #38 for the 16 Mbit, blocks #21 and #22 for the 8
Mbit, blocks #13 and #14 for the 4 Mbit) are lockable.

Check Write State Machine bit first to determine word program
or block-erase completion, before checking program or erase-
status bits.
When erase suspend is issued, WSM halts execution and sets
both WSMS and ESS bits to “1.” ESS bit remains set at “1” until
an Erase Resume command is issued.
When this bit is set to “1,” WSM has applied the max. number
of erase pulses to the block and is still unable to verify
successful block erasure.
When this bit is set to “1,” WSM has attempted but failed to
program a word.

When program suspend is issued, WSM halts execution and
sets both WSMS and PSS bits to “1.” PSS bit remains set to “1”
until a Program Resume command is issued.
If a Program or Erase operation is attempted to one of the
locked blocks, this bit is set by the WSM. The operation
specified is aborted and the device is returned to read status
mode.
This bit is reserved for future use and must be masked out
when polling the Status Register.
