analog on any GPIO pin of CC2640?

Other Parts Discussed in Thread: CC2640

Can the ADC or PWM functions be routed to any of the GPIO pins of the CC2640 or are some of the pins "special" and ADC can only be mapped to them?

    Hi,

    Please see Section 12.3 "I/O Mapping and Configuration" in the CC26xx TRM (SWCU117).

    Best wishes

    This information is also found in the datasheet.

    Thanks for the answer. Just a small correction, in case someone else is looking this up, the section is 11.3.

    And just a small follow up, is mapping the output of a timer for PWM considered an analog function, and therefore only the analog capable GPIO pins can be used?

    It depends on which version of the document you have. It will probably change back to 12.3 :-)

    This is digital. I think it should be clear from the same chapter.
