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.
