qRead Status Register Command
This command reads status information. When the “7016” com-
mand code is transferred with the 1st byte, the contents of the
status register (SRD) with the 2nd byte and the contents of status
register 1 (SRD1) with the 3rd byte are read.
qPage 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) Transfer the “FF16” command code with the 1st byte.
(2) Transfer addresses AB8 to AB15 and AB16 to AB23 with the 2nd
and 3rd bytes respectively.
(3) From the 4th byte onward, data (DB0 to DB7) for the page (256
bytes) specified with addresses AB8 to AB23 will be output se-
quentially from the smallest address first synchronized with the
fall of the clock.
