Note
1:
The Data Memory is only 9-bits wide, so the MSb is ignored by the device.
2:
Increment or Decrement commands are invalid for these addresses.
3:
I2C read operation will read 2 bytes, of which the 10-bits of data are contained within.
4:
Disables WiperLock Technology for wiper 0, wiper 1, wiper 2, wiper3, or disables Write Protect.
5:
Enables WiperLock Technology for wiper 0, wiper 1, wiper 2, wiper3, or enables Write Protect.
