Reset/Power-down. The memory is in Power-
down when the Read Configuration Register is set
for Power-down and RP is at VIL. The power con-
sumption is reduced to the Power-down level, and
Outputs are in high impedance, independent of the
Chip Enable E, Output Enable G or Write Enable
W inputs. The memory is in reset when the Read
Configuration Register is set for Reset and RP is
at VIL. The power consumption is the same of the
standby and the outputs are in high impedance.
After a Reset/Power down the device defaults to
read array mode, the status register is set to 80h
and the read configuration register defaults to
asynchronous read.
Block Locking. Any combination of blocks can
be temporarily protected against Program or
Erase by setting the lock register and pulling WP
to VIL. The following summarizes the locking oper-
ation. All blocks are protected on power-up. They
can then be unprotected or protected with the Un-
protect and Protect commands. The Lock com-
mand protects a block and prevents it from being
unlocked when WP =0. WhenWP = 1, Lock is
overridden. Lock is cleared only when the device
is reset or powered-down (see Protect instruction).
