Note 1:
The data memory is only 9-bits wide, so the MSb is ignored by the device.
2:
All these address/command combinations are valid, so the CMDERR bit is set. Any other address/command combina-
tion is a command error state and the CMDERR bit will be clear.
3:
Increment or Decrement commands are invalid for these addresses.
