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
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.
