30. D/A Converter
The D/A converters are 8-bit R-2R type units. There are two independent D/A converters.
30.1
D/A conversion is performed by writing a value to the DAi register (i = 0 or 1). To output the conversion result, set the
DAiE bit in the DACON register to 1 (output enabled). Before using D/A conversion, set the corresponding bits
PD13_0 and PD13_1 in the PD13 register to 0 (input mode).
The output analog voltage (V) is determined by the setting value n (n: decimal) of the DAi register.
Table 30.1 lists the D/A Converter Specifications. Figure 30.1 shows the D/A Converter Block Diagram and Figure
30.2 shows the D/A Converter Equivalent Circuit.
