Microchip ATSAME53N19A

[mwerezak]

Sorry if this is a dumb question, I'm wondering how much work it would take to add the ATSAME53N19A as a debug target. The website says that SAM D20/D21 are supported, and the Microchip datasheet puts the D5/E5 in the same family, so I'm wondering how difficult it might be to try to debug SAM E5 with the Black Magic Probe.

Also, what would be the best resources to look at to get started with such project?

Thanks
