Fig. 90 Timing for clear status register
Clear Status Register Command
This command clears the bits (SR3 to SR5) which are set when
the status register operation ends in error. When the “50
16
” com-
mand code is sent with the 1st byte, the aforementioned bits are
cleared. When the clear status register operation ends, the SRDY
(BUSY) signal changes from “H” to “L” level.

Page Program Command
This command writes the specified page (256 bytes) in the flash
memory sequentially one byte at a time. Execute the page pro-
gram command as explained here following.
(1) Transfer the “41
16
” command code with the 1st byte.
(2) Transfer addresses AB
8
to AB
15
and AB
16
to AB
23
with the 2nd
and 3rd bytes respectively.
(3) From the 4th byte onward, as write data (DB
0
to DB
7
) for the
page (256 bytes) specified with addresses A
8
to A
23
is input
sequentially from the smallest address first, that page is auto-
matically written.
When reception setup for the next 256 bytes ends, the SRDY
(BUSY) signal changes from “H” to “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.
