This value should consist one or more of the DAC_OPA[opa#]MUX_OUTPEN_OUT[output#] flags (defined in <part_name>_dac.h) OR'ed together. For OPA0:

  • DAC_OPA0MUX_OUTPEN_OUT0

  • DAC_OPA0MUX_OUTPEN_OUT1

  • DAC_OPA0MUX_OUTPEN_OUT2

  • DAC_OPA0MUX_OUTPEN_OUT3

  • DAC_OPA0MUX_OUTPEN_OUT4

For OPA1:

  • DAC_OPA1MUX_OUTPEN_OUT0

  • DAC_OPA1MUX_OUTPEN_OUT1

  • DAC_OPA1MUX_OUTPEN_OUT2

  • DAC_OPA1MUX_OUTPEN_OUT3

  • DAC_OPA1MUX_OUTPEN_OUT4

For OPA2:

  • DAC_OPA2MUX_OUTPEN_OUT0
