I'm planning to design a custom PCB using the ADuCM350. Having a look at the application note AN-1262, I understand that I'll need to pull the kernel gpio high to initiate the serial download.
My question is, in which UART RX port does the ADuCM350 expects the data to be sent? From the datasheet, I believe there are two UART RX ports the P0.7 and P3.7.
Playing around with the EVAL board (with a mass erased ADuCM350) swapping the jumpers M2 and M1, I noticed that the CM3WSD would only program the board using P0.7 and P0.6. Are these the default ports to program the device?
