21.2
21.2.1
The D/A data registers (DADR0 and DADR1) are 8-bit readable/writable registers that store the
data to be converted. When analog output is enabled, the D/A data register values are constantly
converted and output at the analog output pins.
The D/A data registers are initialized to H'00 by a reset.
21.2.2
DACR is an 8-bit readable/writable register that controls the operation of the D/A converter.
DACR is initialized to H'1F by a reset.
Bit 7—D/A Output Enable 1 (DAOE1): Controls D/A conversion and analog output.
Bit 7: DAOE1
