Notes:

1

Data bytes are shifted with Most Significant Bit first. Byte fields with data in parenthesis “( )” indicate data being read from

the device on the DO pin.

2

The Status Register contents will repeat continuously until /CS terminates the instruction.

3

See Manufacturer and Device Identification table for Device ID information.

4

The Device ID will repeat continuously until /CS terminates the instruction.
