Ch XX TM: A one (1) in a field indicates a value has been written to the channel Main DAC Triggered Register, but the output is not enabled until the trigger is received. A zero (0) in a field indicates a trigger will have no effect on the channel. The trigger events are set in the Trigger Control Register.

Notes You can output an immediate value on a channel that has been set for triggered operation by writing a value to the Main_DAC Immediate Register. The trigger mode for that channel is changed to the immediate write-thru mode.

You can set a value on a channel to be applied at the next trigger event by writing a value to the Main_DAC Triggered Register. The trigger status for that channel will be changed to triggered.

Channels 09 through 16 will return ones (1) if the module is configured as an 8-channel device.
