Section 15 D/A Converter
15.2
15.2.1
DADR0, DADR1 are 8-bit readable/writable registers that store data for conversion.
Whenever output is enabled, the values in DADR0 and DADR1 are converted and output from the
analog output pins.
DADR0 and DADR1 are each initialized to H'00 by a reset and in hardware standby mode.
15.2.2
DACR01 is 8-bit readable/writable register that controls the operation of the D/A converter.
DACR01 is initialized to H'1F by a reset and in hardware standby mode.
Bit 7—D/A Output Enable 1 (DAOE1): Controls D/A conversion and analog output.
