Section 17 D/A Converter [Provided in the H8S/2626 Group only]
17.2
17.2.1
DADR2 and DADR3 are 8-bit readable/writable registers that store the data to be converted.
When analog output is enabled, the values in DADR2 and DADR3 are constantly converted and
output at the analog output pins.
The D/A data registers are initialized to H'00 by a reset and in hardware standby mode.
17.2.2
DACR23 is an 8-bit readable/writable register that controls the operation of the D/A converter.
DACR23 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.
