OU_CLK_SRC
Output Unit Conversion Clock Source
These bits select the Output Unit Conversion Clock signal
source. The Output Unit Conversion Clock signal defines the
DAC Sequencer’s Conversion Rate.
Note that in Frame Mode, the Output Unit Conversion Clock
signal must be phase locked to the Frame Trigger signal.

Conversion Clock 1
1
Conversion Clock 2
Setting the DAC Sequencer's Conversion Rate to a
period shorter than the DAC settling time (~10µs) is not
allowed.
If the Output Unit triggers the next conversion as long as the
DAC outputs are still settling from the previous conversion
or the DACs are not properly pre-loaded with DAC Data,
conversion is stopped and the OU_CONV_ERR bit in the
DAC Sequencer Status Register is set.

PRELOAD_CLEAR
Output Unit Pre-Load Clear
Setting this bit marks the DACs operating in Sequencer
Mode as being ‘un-loaded’. The DACs are automatically pre-
loaded again when DAC Data is/becomes available in the
DAC Sequencer's internal FIFO.
This bit is self-clearing.

OU_CONV_START
Output Unit Start Conversion (Normal Mode)
Set this bit to start a conversion process in Normal Mode.
The FIFO Level may be checked before setting this bit.

OU_MODE
Output Unit Mode
0: Normal Mode
1: Frame Mode
In Normal Mode, the configured Number of Conversions is
performed starting with the next Conversion Clock after the
OU_CONV_START bit has been set by software.
In Frame Mode, the configured Number of Conversions is
performed starting with the next Conversion Clock after a
Frame Trigger occurred.
