D-A register 0
Note 1: The above diagram shows an instance in which the D-A register is assigned 2A
Note 2: The same circuit as this is also used for D-A1.
Note 3: To reduce the current consumption when the D-A converter is not used, set the D-A output enable bit to 0 and set the D-A register to 00
