Analog pins as open drain outputs

Hi,

According to AM335x Sitara™ Processors data sheet, AIN3 and AIN4 can be configured as an open-drain outputs. How can I do it? How can I control output?
Thanks in advance for response!

  • The datasheet specify that AIN0..AIN4 can be configured as outputs. Not as a general-purpose outputs however.

    TRM Fig 12.2 shows the details.

    Control of the outputs is performed through touchscreen controller.
