Section 18 D/A Converter
18.5
18.5.1
It is possible to enable/disable the D/A converter operation using the module stop control register,
the D/A converter does not operate by the initial value of the register. The register can be accessed
by releasing the module stop mode. For details, see section 24, Power-Down Modes.
18.5.2
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.
