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.
