Atmel Xmega - some more thoughts

Work continues here in the background on a small development platform based on the ATXmega128A1. One very interesting point which becomes salient with these devices is the peripheral multiplexing issue. Until now the functions available on each pin were minimal - you used a pin as IO or you might assign it to a timer, or a UART.

But with the Xmega we have more choices, how many UARTs can we use while using various SPI or TWI ports? Which functionality do we lose by choosing some other function? Lots of fun and something that we have been insulated from in the AVR world.
