19.5 Usage Notes
19.5.1 Module Stop Function Setting
D/A converter operation can be disabled or enabled using the module stop control register. The
initial setting is for the D/A converter to be halted. Register access is enabled by clearing the
module stop state. For details, see section 24, Power-Down Modes.
19.5.2 D/A Output Hold Function in Software Standby Mode
If D/A conversion is enabled and this LSI enters software standby mode, D/A output is held and
analog power supply current remains at the same level during D/A conversion. When the analog
power supply current is required to go low in software standby mode, bits DAOE and DAE should
be cleared to 0, and D/A output should be disabled.
