Analog Output Update

Analog outputs are updated under program control in either one of two ways:

1)

Automatic Update: Each channel is updated individually when new data are 
written to the related high-byte base address. Individual update mode may be set 
by a special read operation as defined in the programming section of this manual.

OR

2)

Simultaneous Update: The outputs of all D/As may be updated simultaneously. 
This is done by first enabling simultaneous updating for all outputs and then 
preloading the low and high bytes of each DAC and then initiating a 
simultaneous update by software command.

Refer to Chapter 5 of this manual for more detail.
