Read Status (70h)
The Read Status operation is used to read the device
status to determine if the device is ready, in the write
protect mode, erase suspended, or if the previous pro-
gram/erase operation completed without error. After
the rising edge of the command cycle WE# pulse, the
falling edge of CE# or RE#, whichever occurs last, will
output the contents of the status register on the 8 I/O
pins, I/O7–I/O0. The status register is constantly up-
dated and does not require either CE# or RE# to be
toggled. By utilizing the Read Status operation, multi-
ple devices with RY/BY# pins wired together may be
polled to determine their specific status.

Program Operations
Input Data (80h)
The Input Data command sequence is the first of two
operations that must be performed to program infor-
mation into one of the Flash pages. The second
operation, Page Program, is used to transfer informa-
tion from the Data Registers to the Flash array after
the Input Data procedure loads the Data Registers. In
order to set the starting region within the Data Regis-
ters (first half, second half, or Spare Area), the
appropriate command (00h, 01h, 50h) should be is-
sued prior to the Input Data command being
performed. If a command is not submitted to assign
the starting region, the starting region will be deter-
mined by its previous state.
