25.4 Usage Notes
25.4.1 Setting for Module Stop Mode
The module standby control can select to enable/disable the D/A converter operation. The D/A
converter does not operate by the initial value of the register. The register can be accessed by
releasing the module standby mode. DADR is initialized in module standby.
25.4.2 Operation in Standby Mode
If D/A conversion is enabled and this LSI enters standby mode, DADR is initialized while DACR
is held. When the analog power supply current is required to go low in software standby mode, the
DAOE1 and DAOE0 bits should be cleared to 0, and D/A output should be disabled.
