•
DAE2, DAE1, and DAE0 are used to control the output of channel 2, channel 1 and channel
0, respectively.
•
When bit 0 is set to 1, D/A output is enabled. When bit 0 is set to 0, D/A output is disabled.
•
A reset initializes these bits to 0. These bits can be both read and written.
•
When output is disabled, the D/A converter output pins are set to the output level of 0.
