Hi. Please can you give me the address of the avr-gcc developers. I got some questions regarding the code generation of this port. This is the question: Why the interrupt funtions start with a "sei" instrucction? This seems to be a problem for UART interrupts (AT90S2313). If a character is received you must read it from the UDR register before enabling interrupts. Otherwise the interrupt keep nesting until you get a stack overflow.
