Section 18 D/A Converter
18.3
The D/A converter has the following registers.
• D/A data register 2 (DADR2)
• D/A data register 3 (DADR3)
• D/A control register 23 (DACR23)
18.3.1
DADR2 and DADR3 are 8-bit readable/writable registers that store data for conversion.
Whenever analog output is enabled, the values in DADR are converted and output to the analog
output pins.
18.3.2
DACR23 controls the operation of channels 2 and 3 in the D/A converter.
