Let's play pirate

So here we go again. Looking at the schematic. I see there is two ten pin blugs. one is labled "module debug flash" has a 'reset p2.2 and a p2.1, gnd and 3v3. X3 however has quite a bit including uart pins. That seems to go to the FTDI chip. Now P2.2 is E2 on the pan, and P2.1 E1. On the cross reference looks like this is /dd/dc some sort of programming interface. This connects to the debug interface so I looked up the a051 cpu core to see what I could find. that is quite the rabbit hole
