D/A data registers 0 and 1 (DADR0 and DADR1) are 8-bit readable and 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 at a reset and in the standby modes.
