4.5.3

WRITE SUSPEND PROGRAM

STATUS (WSP)

The Write Suspend-Program status (WSP) bit indi-

cates when a Program operation has been suspended.

The WSP is ‘1’ after the host issues a suspend com-

mand during the Program operation. Once the sus-

pended Program resumes, the WSP bit is reset to ‘0’.

4.5.4

WRITE PROTECTION LOCK-DOWN

STATUS (WPLD)

The Write Protection Lock-Down status (WPLD) bit

indicates when the Block-Protection register is locked-

down to prevent changes to the protection settings.

The WPLD is ‘1’ after the host issues a Lock-Down

Block-Protection command. After a power cycle, the

WPLD bit is reset to ‘0’.

4.5.5

SECURITY ID STATUS (SEC)

The Security ID Status (SEC) bit indicates when the

Security ID space is locked to prevent a Write com-

mand. The SEC is ‘1’ after the host issues a Lockout

SID command. Once the host issues a Lockout SID

command, the SEC bit can never be reset to ‘0.’

4.5.6

BUSY

The Busy bit determines whether there is an internal

Erase or Program operation in progress. If the BUSY

bit is ‘1’, the device is busy with an internal Erase or

Program operation. If the bit is ‘0’, no Erase or Program

operation is in progress.
