Hi, 

Atmel ICE specifies pins connections for programming (datasheet): 

 

Pin 3 should be connected to GND. However, pin 3 (PA02) is used for DAC Output later in my application:

 

My question is, is this okay to do? Maybe I am getting something blatantly wrong.  

Pinout of my MCU: Section 4.1.1 here https://cdn.sparkfun.com/datasheets/Dev/Arduino/Boards/Atmel-42181-SAM-D21_Datasheet.pdf  

Thanks.

The numbering refers to the connector on the Atmel ICE (which has two ports for 10-pin connector cables). The pins in question are PA30 and PA31, so Pin 3 on the SAM is not used for programming.
