Silicon Laboratories EFR32xG14 Wireless Gecko Reference Manual page 1133

• Set IDAC_CTRL_APORTOUTSEL = APORT1XCH30. This selects the IDAC APORT output 1X and pin PB14.
• Set IDAC_CTRL_APORTOUTEN = 1 and IDAC_CTRL_APORTOUTENPRS = 0. This enables the IDAC to ungate it's output to
BUSCX.
Another example, when ADC is configured to operate in single channel mode for differential inputs (see
for how to configure ADC in single channel mode), the positive ADC APORT input 2X and the negative ADC APORT input 2Y can be
routed to pin PC9 and PC10 via BUSBX and BUSBY respectively with the following configuration:
• Set ADCn_SINGLECTRL_POSSEL = APORT2XCH9. This selects the pin PC9 for the positive input to the ADC.
• Set ADCn_SINGLECTRL_NEGSEL = APORT2YCH10. This selects the pin PC10 for the negative input to the ADC.
For smaller packages, not all GPIO pins are available. See the pinout sections of the device data sheet for pin availability on a specific
device.
