I'd add that posting such a small section of your code makes it almost impossible for anybody to understand what's going on ( just so you know, for any future code postings ). Did...

SPID STATUS not working. Help please.
You have to put something in the SPID_data register, for it to work. Check out AVR1309 on Atmel's site under 8 bit MCUs ( Xmega ). There's really only rare cases when asm would...

Interrupts on Xmega
When you post about software questions, ALWAYS list the toolchain, and chip you're using, . WHICH Xmega are you using and what problem do you have ? I suggest learning C ......

ADC referense for XMEGA.
Hello Doc.   AFE = Analog Front End. Basically any circuitry, inc. cables/probes, leading up to the ADC input. Ok, I found the 3 wire/color cable set on Sparkfun, thank you...

ADC referense for XMEGA.
DOCJC, where did you get your EKG AFE ( pads, etc ) from ( maybe you built it from scratch... ) ?

ATXMEGA128A3U Clock settings
I can't find any code example. Xmegas have many AppNotes and code examples on the Atmel site. Look for AVR1506.

Problem with SD card / FatFs on SAMV71 Xplained Ultra
These sound like speeds using SPI, am I wrong ? I'd be surprised if your ARM uC didn't have 4 bit SD I/F, but if those speeds ARE for the 4 bit I/F...( ??!!? )
