On other Atmel Micros I work with, I use the SPI or PDI interfaces. 

I am now designing something using the ATmega324PB processor.

The data sheet for the ATmega324PB states that memory can be programmed using the SPI interface.


The question is: can I use the SPI interface for Debug as well or am I better off using JTAG?

I use an Atmel ICE for programming and debug.


Thanks for your help,

The datasheet shows JTAG as on-chip Debug!

So that is the only debug interface on the chip.
