Notes:

1. The Status Register contents and Device ID will repeat continuously until CS# terminates the instruction.

2. At least one byte of data input is required for Page Program, Quad Page Program and Program Security Registers, 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.

3. Write Status Register-1 (01h) can also be used to program Status Register-1&2&3, see section 7.1.5.
