UART Interrupt

Hello all,

I’m going through some of the example programs (namely uartEcho.c), trying to figure out how to use UART interrupts. There’s some functions that look like they do stuff, such as UARTIntEnable() and UARTIsr(). The problem is that they appear to use some flags, and I can’t see what purpose they serve, or what the input arguments even are. I’ve looked in all the associated header files, and I’ve also looked on Google. I still can’t find anything on how to appropriately use these functions.

Does anyone know of any sources that I may refer to?
