Digital-to-Analog Converter Controller (DACC)
43.1
Description
The Digital-to-Analog Converter Controller (DACC) provides up to
2
analog outputs, making it possible for the
digital-to-analog conversion to drive up to
2
independent analog lines.
The DACC supports 12-bit resolution. Data to be converted are sent in a common register for all channels.
External triggers or free-running mode are configurable.
The DACC integrates a sleep mode and connects with a PDC channel. These features reduce both power
The DACC integrates a sleep mode and connects with a PDC channel. These features reduce both power
consumption and processor intervention.
The user can configure DACC timings, such as startup time and refresh period.
