Usage Notes

27.4.1

Module Stop Function Setting

Operation of the 8-bit D/A converter can be disabled or enabled using the module stop control register. The initial setting
is for operation of the 8-bit D/A converter to be stopped. Register access is enabled by releasing the module stop state.
For details, refer to section 11, Low Power Consumption .
27.4.2

Operation of the D/A Converter in Module Stop State

When the MCU enters the module stop state with D/A conversion enabled, the D/A converter outputs are retained, and
the analog power supply current is the same as during D/A conversion. If the analog power supply current has to be
reduced in the module stop state, disable D/A conversion by setting the DACR. and DAOE0 bit to 0.
27.4.3

Operation of the D/A Converter in Software Standby Mode

When the MCU enters software standby mode with D/A conversion enabled, the D/A converter outputs are retained, and
the analog power supply current is the same as during D/A conversion. If the analog power supply current has to be
reduced in software standby mode, disable D/A conversion by setting the DACR. and DAOE0 bit to 0.
27.4.4

Setting the D/A Converter

When using the D/A converter output voltage as a reference input voltage of the comparator C, set the D/A converter and
wait for the D/A converter output settling time (t
changes to the settings of the D/A converter stop the comparator temporarily, and after the changes are made, wait for the
D/A converter output settling time before enabling the comparator.
