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 combi-

nation is a command error state and the CMDERR bit will be clear.

3: Disables WiperLock Technology for wiper 0 or wiper 1, or disables Write Protect.

4: Enables WiperLock Technology for wiper 0 or wiper 1, or enables Write Protect.

5: Reserved addresses: Increment or Decrement commands are invalid for these addresses.
