Address
The Data Memory is only 9-bits wide, so the MSb is ignored by the device.
All these Address/Command combinations are valid, so the CMDERR bit is set. Any other Address/Command combination is a
command error state and the CMDERR bit will be clear.
Disables WiperLock Technology for wiper 0, wiper 1, wiper 2, wiper3, or disables Write Protect.
Enables WiperLock Technology for wiper 0, wiper 1, wiper 2, wiper3, or enables Write Protect.
Increment or Decrement commands are invalid for these addresses.
