23.3

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)

23.3.1

D/A Data Registers 0 and 1 (DADR0 and DADR1)

DADR0 and DADR1 are 8-bit readable/writable registers that store data to which D/A conversion

is to be performed. Whenever an analog output is enabled, the values in DADR are converted and

output to the analog output pins.
