Dear Friends... I am Ramesh, working on project on p89c669 MC. I am facing problem in programming serial interrupts in 8051C for p89c669. it has dual UARTs. what is interrupt no.s used by 8051C for the p89c669. (Interrupt vector table ) Pls suggest some sample pgms on it...
Thanking you...
Ramesh.
What is 8051C? A compiler? In that case - why not post a link?
Have you spent any time going through the documentation for the P89C669 processor? Didn't the user manual for the processor tell you the interrupt vectors for the two UART? There is a specific chapter about interrupts...
