Section 18 D/A Converter
18.2
18.2.1
D/A data registers 0, 1 (DADR0, DADR1) are 8-bit readable/writable registers that store data to
be converted. When analog output is enabled, the value in the D/A data register is converted and
output continuously at the analog output pin.
The D/A data registers are initialized to H'00 by a reset and in hardware standby mode.
18.2.2
DACR01 is an 8-bit readable/writable register that controls the operation of the D/A converter
module.
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.
