The overflow interrupts from Timer0 and Timer2 can still be used for other timing, but the prescalers for these timers must not be changed.<p>Serial output from this UART can be routed to any I/O pin. Serial input for this UART must come from the External Interrupt 2 (INT2) I/O pin. These options should be configured by editing your local copy of "uartsw2conf.h". <p><table border="0" cellpadding="0" cellspacing="0"><tr><td></td></tr></table><hr size="1"><address style="align: right;"><small>Generated on Sun Oct 29 03:41:09 2006 for Procyon AVRlib by&nbsp;<a href="http://www.doxygen.org/index.html"><img src="doxygen.png" alt="doxygen" align="middle" border="0"></a> 1.4.2 </small></address></body></html>
