D/A data registers 0 to 3 (DADR0 to DADR3) 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.

DACR01 and DACR23 are an 8-bit readable/writable register that controls the operation of the
D/A converter module.
DACR01 and DACR23 are initialized to H'1F by a reset and in hardware standby mode.
