D/A Output Control

In the H8/3048 Group, D/A converter output can be enabled or disabled in software standby mode.
When the DASTE bit is set to 1 in DASTCR, D/A converter output is enabled in software standby
mode. The D/A converter registers retain the values they held prior to the transition to software
standby mode.
When D/A output is enabled in software standby mode, the reference supply current is the same as
during normal operation.
