I´d lik to know if someone can get me a C example code for programming the SC28C94 QUART.
I'm having some trouble in controlling the internal interrupt system for this UART, specially when I'm detecting the Tx and Rx interrupt.
My problem is that I can attend both interrupts, but after this the interrupt line wont disable and stays active even after I attend the Rx and the Tx interrupt, even though I can see (read the CIR register) that there are no interrupts to be attended to.
If someone can help me in this matter I'd be much obliged
My best regards.
