Hi,

I'm not too experienced, but I've had the same problem myself and after
testing, I think the solution I have is good. You can define a macro
like that

#define clear_usart_errors_inline
\
if (OERR)
\
{
\
        TXEN=0;
\
        TXEN=1;
\
        CREN=0;
\
        CREN=1;
\
        rstate = 0;
\
}
\
if (FERR)
\
{
\
        i=RCREG;
\
        TXEN=0;
\
        TXEN=1;
\
        rstate = 0;
\
}

and put it before or after (I'm not so sure now where) the reading of
the RCREG or loading of TXREG.
Hope this helps.

Lucian

TXIF is read-only.
