The content of 8-bit D/A converter is divided into D/A MSB data register (DAMSB) and D/A LSB data
register (DALSB). The block diagram is shown below.

When the DACTL register bit0 is set by software, the 8-bit D/A converter starts converting. The only
way to disable the D/A converter is to reset the bit0 of the DACTL register using the software control.
The power source of the D/A converter can be selected from the (2/3)V

or 1.5V by programming
the DACTL register bit2.
