Page Read Command
This command reads the specified page (256 bytes) in the flash memory sequentially one byte at a
time. Execute the page read command as explained here following.
(1) Send the “FF
16
” command code in the 1st byte of the transmission.
(2) Send addresses A
8
to A
15
and A
16
to A
23
in the 2nd and 3rd bytes of the transmission respec-
tively.
(3) From the 4th byte onward, data (D
0
–D
7
) for the page (256 bytes) specified with addresses A
8
to
A
23
will be output sequentially from the smallest address first in sync with the rise of the clock.

Read Status Register Command
This command reads status information. When the “70
16
” command code is sent in the 1st byte of the
transmission, the contents of the status register (SRD) specified in the 2nd byte of the transmission
and the contents of status register 1 (SRD1) specified in the 3rd byte of the transmission are read.
