Section 19 D/A Converter
19.2
19.2.1
D/A data registers 0 and 1 (DADR0 and 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.
19.2.2
DACR is an 8-bit readable/writable register that controls the operation of the D/A converter
module.
DACR 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.
