17.5 Usage Notes
17.5.1 Module Stop Mode Setting
Operation of the D/A converter can be disabled or enabled using the module stop control register.
The initial setting is for operation of the D/A converter to be halted. Register access is enabled by
clearing module stop mode. For details, refer to section 24, Power-Down Modes.
17.5.2 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.
