When this LSI enters software standby mode with A/D conversion enabled, the analog inputs are
retained, and the analog power supply current is equal to the current as during A/D 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 A/D conversion.
