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) Transfer the “FF16” command code with the 1st byte.

(2) Transfer addresses A8 to A15 and A16 to A23 with the 2nd and 3rd bytes respectively.

(3) From the 4th byte onward, data (D0–D7) for the page (256 bytes) specified with addresses A8 to

A23 will be output sequentially from the smallest address first.

Read Status Register Command

This command reads status information. When the “7016” command code is sent with the 1st byte, the

contents of the status register (SRD) specified with the 2nd byte and the contents of status register 1

(SRD1) specified with the 3rd byte are read.
