There is no need for error recovery in this function.
Interrupt Servicing
General ISR Routines
The porting of an ISR routine between platforms is a rather difficult task. There are so many
different implementations of the hardware level routines that creating a universal routine is
impossible.
In this driver, the user is responsible for creating a ‘shell’ (
in turn calls an API function,
the ISR related housekeeping that is required by the device. This method was chosen because it
places the burden of determining which device(s) is(are) requesting service on the user, rather
than attempting to incorporate the many possible hardware scenarios into the driver.
During execution of the API function
informs the application that it is time to install (uninstall) this ‘shell’ via the user supplied
function:
Note: A device can be initialized with interrupts disabled. In that mode, a polling routine can be
invoked independently that in-turn processes the interrupt status in the device.
Installing Interrupt Handlers: sysTemuxISRHandlerInstall
This function installs the user-supplied Interrupt-Service Routine,
the processor’s interrupt vector table.
