Latch mode selection for channels.
|
|
0 means the channel is not latched, 1 means latched.
|
|
The default settings to non latched should be more straightforward to use than the latched
|
|
mode. The latch mode can be used eitheir with the ldac-gpios to load both channels at the
|
|
same time or if no ldac-gpios property is set, latching will be done per channel with a
|
|
register write.
