Status Register
The Status Register provides information on the current or
previous program or erase operations. A Read Status
Register command is issued to read the contents of the
Status Register, refer to
page 14
Register is latched and updated on the falling edge of the
Chip Enable or Output Enable signals and can be read until
Chip Enable or Output Enable returns to V
The Status Register can only be read using single
asynchronous or synchronous reads. Bus Read operations
from any address within the bank always read the Status
Register during program and erase operations if no Read
Array command is issued.

The various bits convey information about the status and
any errors of the operation. Bits SR7, SR6, SR2 and SR0
give information on the status of the device and are set and
reset by the device. Bits SR5, SR4, SR3 and SR1 give
information on errors and are set by the device but must be
reset by issuing a Clear Status Register command or a
hardware reset.
If an error bit is set to ‘1’, the Status Register should be
reset before issuing another command.
The bits in the Status Register are summarized in
