Direct DC

Hey guys,

Anyone knows what is “Direct DC” ?
It seems to be a protocol with 4 out, 1 in & 1 clock.
I didn’t find any documentation on these which is bounded on pins U24(CLK), U23(IN), U31-V31-V26-V29(OUT [0…3]) on the TK1.

It is unused by the Jetson TK1 but it intrigues me ^^.

have a nice day,

It’s a high-speed debug/trace interface
