Questions about ddr registers

Mar 19, 2021


Which forum do we belong on for questions about ddr registers? Can anyone help??

You can read about the DDRn (Data Direction Register for Port n) in the processor data sheet.

Split from an unrelated topic

What do you want to ask?

Thanks.. Tom... :slight_smile:

DDRs are processor specific, each one may be different and not all may be the same on any specific processor. The best source of information is the data sheet, and they can run several hundred pages. In the Arduino arena the PinMode sets the DDR. What specific processor are you interested in and have you downloaded the data sheet and read it?
