MX29LV320M H/L

Toggle Bit. If Q3 is low ("0"), the device will accept addi-

tional sector erase commands. To insure the command

has been accepted, the system software should check

the status of Q3 prior to and following each subsequent

sector erase command. If Q3 were high on the second

status check, the command may not have been accepted.

If the time between additional erase commands from the

system can be less than 50us, the system need not to

monitor Q3.

Q1: Write-to-Buffer Abort

Q1 indicates whether a Write-to-Buffer operation was

aborted. Under these conditions Q1 produces a "1". The

system must issue the Write-to-Buffer-Abort-Reset com-

mand sequence to return the device to reading array data.

See Write Buffer section for more details.

RY/BY#:READY/BUSY OUTPUT

The RY/BY# is a dedicated, open-drain output pin that

indicates whether an Embedded Algorithm is in progress

or complete. The RY/BY# status is valid after the rising

edge of the final WE# pulse in the command sequence.

Since RY/BY# is an open-drain output, several RY/BY#

pins can be tied together in parallel with a pull-up resistor

to VCC .

If the output is low (Busy), the device is actively erasing

or programming. (This includes programming in the Erase

Suspend mode.) If the output is high (Ready), the device

is ready to read array data (including during the Erase

Suspend mode), or is in the standby mode.
