OEMInterruptEnable (Compact 2013)
This function performs hardware operations necessary to enable the specified hardware interrupt.
This function performs hardware operations necessary to allow a device to generate the specified interrupt. This can include
Setting a hardware priority for the device
Setting a hardware interrupt enable port
Clearing pending interrupt conditions from the device
These actions can be split between the device driver and the code in this function.
In general, actions that involve shared state among multiple devices should be managed by the OAL functions, and actions that involve private state should be managed by the device driver.
When a device driver calls the InterruptInitialize kernel routine, the kernel then calls this function.
The system cannot be pre-empted when this function is called.
