UBRR0H display seems to be wrong
The high byte of the baudrate register is always supposed to be zero in my code. AVR Studio version 4.15 usually shows it to be non-zero. The only exception I've seen is when...

Does anyone understand the UART connections on the DB101 board? There are 4 connections besides ground. RXH, TXH, RXL and TXL. So which ones do I use? Atmel's doc8073.pdf "...
