Bit 6—D/A Output Enable 0 (DAOE0): Controls D/A conversion and analog output for channel
0.
Bit 5—D/A Enable (DAE): The DAOE0 and DAOE1 bits both control D/A conversion. When
the DAE bit is cleared to 0, the channel 0 and 1 D/A conversions are controlled independently.
When the DAE bit is set to 1, the channel 0 and 1 D/A conversions are controlled together.
Output of resultant conversions is always controlled independently by the DAOE0 and DAOE1
bits.
If the H8S/2345 Group enters software standby mode when D/A conversion is enabled, the D/A
output is held and the analog power current is the same as during D/A conversion. When it is
necessary to reduce the analog power current in software standby mode, clear the DAE, DAOE0
and DAOE1 bits to 0 to disable D/A output.
Bits 4 to 0—Reserved: Read-only bits, always read as 1.
