Function explanation : [Function explanation]

Simulation : [AD conversion]

This shows the register in which the results of AD conversion performed by AD converter (unit B). Repeating and scanning time of AD conversion are set very slow. 
After setting the conditions, click on the normal conversion start button. The value of the virtual AD input is converted to digital, and then the value is displayed as the result of the conversion. 
The virtual AD input is changed automatically by clicking the start button, and that change is stopped by clicking the Stop button.

Setting method

  • Fixed-channel single conversion mode
    • Select the channel converted by "specify channel."
  • Channel scan single conversion mode
    • Select the channel converted by "specify channel."
    • Select the interrupt generation timing from "Interrupt timing in fixed channel repeat conversion mode." If the conversion is performed each time, the conversion result is always stored in ADBREG00, and AD conversion end interrupt is generated at the end of every conversion. If the conversion is performed every two times, the first result is stored in ADBREG00, and the second result is stored in ADBREG01. Then, after the completion of the second conversion, the AD conversion end interrupt is generated.
  • Fixed-channel repeat conversion mode
    • Select the first channel to start the conversion from "First channel at channel scan."
    • Select the number of channels to convert from "Scanning range at channel scan." If the first channel is AINB0, the number of channels can be up to 12 channels. If the first channel is AINB1, the number of channels can be up to 11 channels.
    • The AD conversion end interrupt is generated when the AD conversion is completed as many channels as the user selected.
  • Channel scan repeat conversion mode
    • Select the first channel to start the conversion from "First channel at channel scan."
    • Select the number of channels to convert from "Scanning range at channel scan." If the first channel is AINB0, the number of channels can be up to 12 channels. If the first channel is AINB1, the number of channels can be up to 11 channels.
    • The AD conversion end interrupt is generated each time when the AD conversion is completed as many channels as the user selected.
