15. D/A Converter
15.2.3
DASTCR is an 8-bit readable/writable register that enables or disables D/A output in software
standby mode.
DASTCR is initialized to H'FE by a reset and in hardware standby mode. It is not initialized in
software standby mode.
Bits 7 to 1—Reserved: These bits cannot be modified and are always read as 1.
Bit 0—D/A Standby Enable (DASTE): Enables or disables D/A output in software standby
mode.

15.3
The D/A converter has two built-in D/A conversion circuits that can perform conversion
independently.
D/A conversion is performed constantly while enabled in DACR. If the DADR0 or DADR1 value
is modified, conversion of the new data begins immediately. The conversion results are output
when bits DAOE0 and DAOE1 are set to 1.
