2.8.2 D-A Converter Operation
The following is the D-A converter operation. Figure 2.8.3 shows the set-up procedure.
Operation (1) Writing a value to the D-A register starts D-A conversion.
(2) Setting the D-Ai output enable bit to “1” outputs an analog signal on the DAi pin.
(3) The D-A converter continues outputting an analog signal until the D-A output enable bit is set
to “0”.
