Data Sheet
Busy
The Busy bit determines whether there is an internal Erase or Program operation in progress. A ‘1’ for
the Busy bit indicates the device is busy with an operation in progress. A ‘0’ indicates the device is
ready for the next valid operation.
Write Enable Latch (WEL)
The Write-Enable-Latch bit indicates the status of the internal memory Write Enable Latch. If the
Write-Enable-Latch bit is set to ‘1’, it indicates the device is Write enabled. If the bit is set to ‘0’ (reset),
it indicates the device is not Write enabled and does not accept any memory Write (Program/Erase)
commands. The Write-Enable-Latch bit is automatically reset under the following conditions:

Power-up
Write-Disable (WRDI) instruction completion
Write-Status Register instruction completion
Page-Program instruction completion
Dual-Input Page-Program instruction completion
Sector-Erase instruction completion
Block-Erase instruction completion
Chip-Erase instruction completion
Program SID instruction completion
Lockout SID instruction completion
Block Protection (BP3,BP2, BP1, BP0)
The Block-Protection (BP3, BP2, BP1, BP0) bits define the size of the memory area, as shown in Table
5, to be software protected against any memory Write (Program or Erase) operation. The Write-Status-
Register (WRSR) instruction is used to program the BP3, BP2, BP1 and BP0 bits as long as WP# is
high or the Block-Protect-Lock (BPL) bit is 0. Chip-Erase can only be executed if Block-Protection bits
are all 0. After power-up, BP3, BP2, BP1 and BP0 are set to the defaults specified in Table 5.
Block Protection Lock-Down (BPL)
WP# pin driven low (V IL ), enables the Block-Protection-Lock-Down (BPL) bit. When BPL is set to 1, it pre-
vents any further alteration of the BPL, BP3, BP2, BP1, and BP0 bits. When the WP# pin is driven high
(V IH ), the BPL bit has no effect and its value is “Don’t Care”. After power-up, the BPL bit is reset to 0.
