PRELIMINARY
Interface software that initiates and polls
progress of block erase, programming, and lock-
bit configuration can be stored in any block. This
code is copied to and executed from system
RAM during flash memory updates. After
successful completion, reads are again possible
via the Read Array command. Block erase
suspend allows system software to suspend a
block erase to read or write data from any other
block. Program suspend allows system software
to suspend a program to read data from any
other flash memory array location.

Data Protection
Depending on the application, the system
designer may choose to make the V
PP
power
supply switchable or hardwired to V
PPH1/2/3
. The
device supports either design practice, and
encourages optimization of the processor-
memory interface.
When V
PP
≤
V
PPLK
, memory contents cannot be
altered. When high voltage is applied to V
PP
, the
two-step block erase, program, or lock-bit
configuration
command
protection from unwanted operations. All write
functions are disabled when V
CC
voltage is below
the write lockout voltage V
LKO
or when RP# is at
V
IL
. The device’s block locking capability
provides additional protection from inadvertent
code or data alteration.

BUS OPERATION
The local CPU reads and writes flash memory in-
system. All bus cycles to or from the flash
memory conform to standard microprocessor bus
cycles.
