Individual block locking uses a combination of block
lock-bits to lock and unlock blocks. Block lock-bits
gate block erase, full chip erase, program and write
to
operations (Set Block Lock-Bit and Clear Block
Lock-Bits commands) set and clear lock-bits.
The status register and the STS pin in RY/BY#
mode indicate whether or not the device is busy
executing an operation or ready for a new
command. Polling the status register, system
software retrieves WSM feedback. STS in RY/BY#
mode gives an additional indicator of WSM activity
by providing a hardware status signal. Like the
status register, RY/BY#-low indicates that the WSM
is performing a block erase, program, or lock-bit
operation. RY/BY#-high indicates that the WSM is
ready for a new command, block erase is
suspended (and program is inactive), program is
suspended, or the device is in deep power-down
mode.
The Automatic Power Savings (APS) feature
substantially reduces active current when the
device is in static mode (addresses not switching).

The BYTE# pin allows either x8 or x16 read/writes
to the device. BYTE# at logic low selects 8-bit
mode with address A
byte and high byte. BYTE# at logic high enables
16-bit operation with address A

pins are at V
standby mode. Driving RP# to GND enables a deep
power-down mode which significantly reduces
power consumption, provides write protection,
resets the device, and clears the status register. A
