Description

DAOE1

R/W

D/A Output Enable 1

Controls D/A conversion and analog output for channel 1.

0: Analog output of channel 1 (DA1) is disabled

1: D/A conversion of channel 1 is enabled. Analog output

of channel 1 (DA1) is enabled.

DAOE0

R/W

D/A Output Enable 0

Controls D/A conversion and analog output for channel 0.

0: Analog output of channel 0 (DA0) is disabled

1: D/A conversion of channel 0 is enabled. Analog output

of channel 0 (DA0) is enabled.

DAE

D/A Enable

Used together with the DAOE0 and DAOE1 bits to control

D/A conversion. Output of conversion results is always

controlled by the DAOE0 and DAOE1 bits. For details,

see table 18.3.

0: D/A conversion for channels 0 and 1 is controlled

independently

1: D/A conversion for channels 0 and 1 is controlled

together
