OTP Register Program
Active Operation
OTP Register, Device Information, CFI Query.
When the Resume command is issued during a simultaneous erase-suspend/ program-
suspend condition, the programming operation is resumed first. Upon completion of the
programming operation, the Status Register should be checked for any errors, and
cleared. The resume command must be issued again to complete the erase operation.
Upon completion of the erase operation, the Status Register should be checked for any
errors, and cleared.
Simultaneous Operations
The multi-partition architecture of the flash device allows programming or erasing to
occur in one partition while reads are performed from another partition. Only status
reads are allowed in partitions that are busy programming or erasing.
When OTP Registercommands are issued to a parameter any partition address, the OTP
Registeris mapped onto that partition.

reading from a partition while simultaneously programming or erasing within another
partition.
Security
The flash device incorporates features for protecting main-array contents and for
implementing system-level security schemes. The following sections describe the
available features.
Block Locking
Two methods of block-lock control are available: software and hardware. Software
control uses the Block Lock and Block Unlock commands; hardware control uses WP#
along with the Block Lock-Down command.
Upon power up or exit from reset, all main array blocks are locked, but not locked
down. Locked blocks cannot be erased or programmed.
Block lock and unlock operations are independent of the voltage level on V
