NOTE : Column Address : Starting Address of the Register.
00h Command(Read) : Defines the starting address of the 1st half of the register.
01h Command(Read) : Defines the starting address of the 2nd half of the register.
* A8 is set to "Low" or "High" by the 00h or 01h Command.
* The device ignores any additional input of address cycles than reguired.
