Write-Lock Bit
The Write-Lock bit, bit 0, controls the lock state described in Table 15. The default Write status of all
blocks after power up is write locked. When bit 0 of the Block Locking register is set, Program and
Erase operations for the corresponding block are prevented. Clearing the Write-Lock bit will unprotect
the block. The Write-Lock bit must be cleared prior to starting a Program or Erase operation since it is
sampled at the beginning of the operation. The Write-Lock bit functions in conjunction with the hard-
ware Write Lock pin TBL# for the top Boot Block. When TBL# is low, it overrides the software locking
scheme. The top Boot Block Locking register does not indicate the state of the TBL# pin. The Write-
Lock bit functions in conjunction with the hardware WP#/AAI pin for the remaining blocks (Blocks 0 to
33 for 49LF016C). When WP#/AAI is low, it overrides the software locking scheme. The Block Locking
register does not indicate the state of the WP#/AAI pin.
Lock-Down Bit
The Lock-Down bit, bit 1, controls the Block Locking register as described in Table 15. When in LPC
interface mode, the default Lock Down status of all blocks upon power-up is not locked down. Once the
Lock-Down bit is set, any future attempted changes to that Block Locking register will be ignored. The
Lock-Down bit is only cleared upon a device reset with RST# or INIT# or power down. Current Lock
Down status of a particular block can be determined by reading the corresponding Lock-Down bit.
Once a block’s Lock-Down bit is set, the Read-Lock and Write-Lock bits for that block can no longer be
modified: the block is locked down in its current state of read/write accessibility.
Read-Lock Bit
The default read status of all blocks upon power-up is read-unlocked. When a block’s read lock bit is
set, data cannot be read from that block. An attempted read from a read-locked block will result in the
data 00h. The read lock status can be unlocked by clearing the read lock bit: this can only be done pro-
vided that the block is not locked down. The current read lock status of a particular block can be deter-
mined by reading the corresponding read-lock bit.
