TMS320F28P650DK: Analog GPIO

Irene Boben

Part Number: TMS320F28P650DK

Hi team,

As per the GPIO chapter, GPIO42 and GPIO43 are Analog GPIOs i.e. can be configured as digital GPIO or Analog input. I can see GPBAMSEL register in GpioCtrlRegs. However, I cannot see the counterpart 'AGPIOCTRLB' in analog subsystem registers.

So if I want to use these GPIOs as an Analog input, which Analog subystem register should I refer?

Thanks and regards,

Irene

Hi Irene,

Thanks for your question. I will ask the device experts to update this, it should have AGPIOCTRLB and the others in there.

Regards,

Vince

After double-confirming with device owner, this is actually incorrect. GPIO42 and GPIO43 are not analog GPIOs. They are standard GPIOs. There is no need for a AGPIOCTRLB register as there is no AGPIO in that range.
