Data bytes are shifted with Most Significant Bit first. Byte fields with data in parenthesis “()” indicate data being read from the device on the I/O pin.

SR = status register, The Status Register contents and Device ID repeats continuously until CS terminates the instruction.

At least one byte of data input is required for Page Program, Quad Page Program and Program Security Register, up to 256 bytes of data input. If more

than 256 bytes of data are sent to the device, the addressing will wrap to the beginning of the page and overwrite previously sent data.

See Manufacturer and Device Identification table for Device ID information.

SC = security register.
