Program Example (Delayed DAC Update Mode)

In the programming example in “Test Mode Programming” on page 3-7, all eight DAC converters were loaded with a full scale value of FFFH in the IMMEDIATE UPDATE MODE. For illustration purposes the same result will be obtained by this programming example by using the DELAYED DAC UPDATE MODE. The DELAYED DAC MODE is jumper-selectable as described in “Program Controlled and External Start Convert Mode” on page 2-9.

The programming sequence in a flowchart is shown in Figure 3-2 on page 3-12. In the following program example all eight DAC channels are loaded with new data, and then updated under program control. Alternatively, if previously enabled, an external trigger input could have initiated the DAC conversion process.
