Functions | |
void | XUartNs550_SetHandler (XUartNs550 *InstancePtr, XUartNs550_Handler FuncPtr, void *CallBackRef) |
void | XUartNs550_InterruptHandler (XUartNs550 *InstancePtr) |
|
This function is the interrupt handler for the 16450/16550 UART driver. It must be connected to an interrupt system by the user such that it is called when an interrupt for any 16450/16550 UART occurs. This function does not save or restore the processor context such that the user must ensure this occurs.
|
|
This function sets the handler that will be called when an event (interrupt) occurs in the driver. The purpose of the handler is to allow application specific processing to be performed.
There is no assert on the CallBackRef since the driver doesn't know what it is (nor should it) |
