Figure 2.8.2. D-A converter-related registers
2.8.1 Overview of the D-A converter usage
The D-A converter used in the M16C/62A group is based on the 8-bit R-2R technique.
(1) Output voltage
(2) Conversion time
(3) Output from the D-A converter and the direction register
(4) Pins related to the D-A converter
(5) Registers related to the D-A converter
(6) Note
The D-A converter outputs voltage within a range from 0 V to V
by V
The D-A converter is not effected by the Vref connection bit of the A-D converter.
tsu = 3 s
To use the D-A converter, do not set the direction register of the relevant port to output.
