Page Read Command
Read Status Register 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.
This command reads status information. When the “70
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.
