1) why all the _asm and _endasm what is wrong with e.g. TI = 0; instead of doing it in assembly (clr TI)?
2) why do you process transmit outside the ISR that WILL slow you down 3) clr es and setb es in the ISR are not needed. 4) the reason for your slowdown is 2). if you for some silly reason want to keep transmit outside the ISR you need, at least, to handle TI inside the ISR. Erik |
