If all you have to do in C is give the function a specific name, then your project is using weak binding to select the interrupt handler. In this case, all you need to do is create an assembly function with the correct symbol name. With EABI, this should be the same as the C function name.

WebInterrupts solve this problem by instead letting the device notify the CPU of an event, such as the UART receiving a new data byte. If you read the manual for the PL011 UART in the previous chapter, you probably remember seeing some registers that control interrupt settings, which we ignored at the time.
