17.3.2 D/A Control Registers 01 and 23 (DACR01, DACR23)
DACR01 and DACR23 control the operation of the D/A converter.
DACR01
Bit Bit Name Initial Value R/W Description
7 DAOE1 0 R/W D/A Output Enable 1
Controls D/A conversion and analog output.
0: Analog output (DA1) is disabled
1: Channel 1 D/A conversion is enabled; analog
output (DA1) is enabled
6 DAOE0 0 R/W D/A Output Enable 0
Controls D/A conversion and analog output.
0: Analog output (DA0) is disabled
1: Channel 0 D/A conversion is enabled; analog
output (DA0) is enabled
5 DAE 0 R/W D/A Enable
Used together with the DAOE0 and DAOE1 bits to
control D/A conversion. When the DAE bit is
cleared to 0, channel 0 and 1 D/A conversions are
controlled independently. When the DAE bit is set
to 1, channel 0 and 1 D/A conversions are
controlled together.
Output of conversion results is always controlled
independently by the DAOE0 and DAOE1 bits. For
details, see table 17.2.
