Page Program Command
This command writes the specified page (256 bytes) in the flash memory sequentially one byte at a
time. Execute the page program command as explained here following.
(1) Send the “4116” command code in the 1st byte of the transmission.
(2) Send addresses A8 to A15 and A16 to A23 in the 2nd and 3rd bytes of the transmission respectively.
(3) From the 4th byte onward, as write data (D0–D7) for the page (256 bytes) specified with addresses
A8 to A23 is input sequentially from the smallest address first, that page is automatically written.
When reception setup for the next 256 bytes ends, the P53 (BUSY) signal changes from the “H” to the
“L” level. The result of the page program can be known by reading the status register. For more
information, see the section on the status register.

Clear Status Register Command
This command clears the bits (SR3–SR4) which are set when the status register operation ends in
error. When the “5016” command code is sent in the 1st byte of the transmission, the aforementioned
bits are cleared. When the clear status register operation ends, the P53 (BUSY) signal changes from
the “H” to the “L” level.
