6.4.1 Toggle Mode

Each DAC in the device is independently configurable to operate in toggle mode. A DAC channel in toggle mode incorporates two DAC registers (Register A and Register B) and is able to be set to switch repetitively between these two values. The DACx1416 toggle mode operation is configurable to introduce a dither signal to the DAC output, to generate a periodic signal, or to implement ON/OFF signaling, among some examples.

To update the toggle registers, use the following sequence:

  1. Set DAC channel in synchronous mode and disable toggle mode for that channel
  2. Write the desired Register A value to the DAC data register
  3. Issue a DAC trigger signal to load Register A
  4. Write the desired Register B value to the DAC data register
  5. Enable toggle mode to load Register B

After both registers are loaded with data, use any of the three TOGGLE[2:0] pins to switch those DACs configured for toggle operation back and forth between the contents of the two respective DAC specific registers by using an external clock or logic signal. A TOGGLE pin logic low updates the DAC output to the value set by Register A. A logic high updates the DAC output to the value set by Register B. The three TOGGLE[2:0] pins give the DACx1416 the option to operate with up to three toggle rates.

Additionally, the device is configurable for software-controlled toggle operation by setting the SOFTTOGGLE-EN bit. In this mode, use any of the three AB-TOG[2:0] bits as a toggle control signal. Setting the AB-TOG bit to 1 enables Register B and clearing this bit to 0 enables Register A.
