OU_CONV_ACTIVE
Output Unit Conversion Process Active
Indicates that the conversion process is active.
In Normal Mode, this bit is set when the software sets the
Output Unit Start Conversion bit. This bit is cleared when
the configured Number of Conversions has been
performed.
In Frame Mode, this bit is set when a Frame Trigger starts
the conversion process (except in a frame error case).
This bit is cleared when the configured Number of
Conversions has been performed (for a single frame).

PRELOAD
Output Unit Pre-Load Done
Indicates that all DACs configured to Sequencer Mode
are pre-loaded with DAC Data on all four DAC Channels.
This bit is automatically cleared upon a DAC conversion
pulse or when the software sets the Output Unit Pre-Load
Clear bit.

DAC_SEQ_NUM_CONV
Number of Conversions to be performed
Set to '0' for continuous digital-to-analog conversions.
Normal Mode:
Number of conversions (after OU_CONV_START was set)
per requested block of digital-to-analog conversions.
When the configured Number of Conversions has been
performed, the conversion process is stopped (until software
sets the OU_CONV_START bit again) and the
OU_CONV_ACTIVE bit in the DAC Sequencer Status
Register is cleared.
Frame Mode:
Number of digital-to-analog conversions per Frame Trigger.
When the configured Number of Conversions (per frame)
has been performed, the conversion process is stopped
(until the next Frame Trigger event occurs) and the
OU_CONV_ACTIVE bit in the DAC Sequencer Status
Register is cleared.

Table 3-44: Number of Conversions Register
Note that every time the DAC Sequencer triggers a conversion, all four DAC Channels of all DACs
configured to operate in Sequencer Mode are updated simultaneously. After each sequencer
controlled conversion, the DACs are pre-loaded with DAC Data for the next conversion (if data is
available in the
DAC Sequencer's internal FIFO).
