Address
The Data Memory is only 9-bits wide, so the MSb is ignored by the device.
Increment or Decrement commands are invalid for these addresses.
I
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.

Function
C read operation will read 2 bytes, of which the 10-bits of data are contained within.
