16.3 Register Descriptions
The D/A converter has the following registers.
• D/A data register 0 (DADR0)
• D/A data register 1 (DADR1)
• D/A control register 01 (DACR01)
16.3.1 D/A Data Registers 0 and 1 (DADR0 and DADR1)
DADR is an 8-bit readable/writable register that stores data to which D/A conversion is to be
performed. Whenever analog output is enabled, the values in DADR are converted and output to
the analog output pins.
