BC127 AIO_1 pin

Hello,

Trying to use pin number 12 of BC127, named “AIO_1”.
This pin is described as “Analog programmable input/output line” in the product technical specification.

I want to use this pin as an ADC input.
Can this be done?
How does one “program” this pin?
How can I read the voltage level of this pin input?

Any response will be really appreciated.
I’ve looked all over and can’t find any reference to this pin except for in being mentioned in the product technical specification manual.

Thanks!

Issue still relevant.
I can’t get this pin to operate as an analog input.
Help, anyone?

Thanks

The only configuration I know of is in the GPIO_CONFIG command. See Melody 6.1.5 manual.
