uint32_t OPAMP_Init_TypeDef::outPen

Alternate output enable bit mask. 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
  • DAC_OPA2MUX_OUTPEN_OUT1

E.g:
init.outPen = DAC_OPA0MUX_OUTPEN_OUT0 | DAC_OPA0MUX_OUTPEN_OUT2 | DAC_OPA0MUX_OUTPEN_OUT4;
