D/A Output Hold Function in Software Standby Mode

When this LSI enters software standby mode with D/A conversion enabled, the D/A outputs are
retained, and the analog power supply current is equal to as during D/A conversion. If the analog
power supply current needs to be reduced in software standby mode, clear the ADST, TRGS1, and
TRGS0 bits all to 0 to disable D/A conversion.
