Command Interface
All Bus Write operations to the memory are interpreted by the command interface.
Commands consist of one or more sequential Bus Write operations. Failure to observe a
valid sequence of Bus Write operations will result in the memory returning to Read mode.
The long command sequences are imposed to maximize data security.
The address used for the commands changes depending on whether the memory is in 16-
bit or 8-bit mode.
Standard commands
See either
summary of the standard commands.
Read/Reset command
The device enters read mode of main array memory after a reset or power-up sequence.
The Read/Reset command returns the memory to Read mode. It also resets the errors in
the Status Register. Either one or three Bus Write operations can be used to issue the
Read/Reset command.
The Read/Reset command can be issued, between Bus Write cycles before the start of a
program or erase operation, to return the device to Read mode. If the Read/Reset command
is issued during the time-out of a Block erase operation, the memory will take up to 10 µs to
abort. During the abort period no valid data can be read from the memory.
The Read/Reset command will not abort an Erase operation when issued while in Erase
Suspend.
Auto Select command
The Auto Select command puts the device in Auto Select mode, once in Auto Select mode,
the system can read the manufacturer code, the device code, the protection status of each
block (Block Protection status) and the Extended Memory Block protection indicator.
Three consecutive Bus Write operations are required to issue the Auto Select command.
Once the Auto Select command is issued Bus Read operations to specific addresses output
the manufacturer code, the device code, the Extended Memory Block protection indicator
and a block protection status (see
