0 1: Start AD Conversion (set by firmware).

1 0: When AD conversion is finished and has moved digital data into the AD Data Register, this bit will be set by hardware.

NOTE

Hardware can enable this function only at AD Channel Select of the functional I/O port. After a power-on reset, the initial value of this register is 0b0001_1111.
