Hello,
I've noticed that my UART_Isr interrupt sometimes gets executed, but when I read the Interrupt type from the INTID bits, it returns 0 which according to the documentation is "Reserved". What is creating these kinds of interrupts and how can I prevent this? 10% of the executions of the interrupt are caused because of this unknown cause.
I'm running the UART in FIFO mode with Transmitter holding register empty interrupt enable, and Receiver data available interrupts enabled...
Cheers!
