Bit 6—D/A Output Enable 0 (DAOE0): Controls D/A conversion and analog output.

Description
Analog output DA0 (DA2) is disabled
(Initial value)
D/A conversion is enabled on channel 0. Analog output DA0 (DA2) is enabled
Bit 5—D/A Enable (DAE): Controls D/A conversion, in combination with bits DAOE0 and
DAOE1. D/A conversion is controlled independently on channels 0 and 1 when DAE = 0.
Channels 0 and 1 are controlled together when DAE = 1.
Output of the converted results is always controlled independently by DAOE0 and DAOE1.

*: Don’t care
If the H8S/2633 Series chip enters software standby mode while D/A conversion is enabled, the
D/A output is retained and the analog power supply current is the same as during D/A conversion.
If it is necessary to reduce the analog power supply current in software standby mode, disable D/A
output by clearing both the DAOE0 and DAOE1 bits to 0.
Bits 4 to 0—Reserved: These bits cannot be modified and are always read as 1.
