Jul 2, 2010
Address: FFF5CH
Notes 1.
Remark The positive reference voltage of the D/A converter is as follows, according to the DAREF, VRSEL and
Symbol
DAM
This register controls the operation of the D/A converter.
DAM can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears this register to 00H.

VRON settings.
The reference voltage of the D/A converter cannot be specified separately for each channel because it is
common to both channels.
To use an output voltage of the voltage reference for the positive reference voltage of the D/A converter
(DA
13 VOLTAGE REFERENCE). Furthermore, do not change the voltage reference setting during the D/A
conversion operation.
