/* Summary
Initialize the interrupt manager module
Description
This function is called to initialize the interrupt module.
This module enables interrupts as well as servies West Bridge
related interrupts by determining the source of the interrupt
and calling the appropriate handler function.
Notes
If the dmaintr parameter is TRUE, the initialization code
initializes the interrupt mask to have the DMA related interrupt
enabled via the general purpose interrupt. However, the interrupt
service function assumes that the DMA interrupt is handled by the
HAL layer before the interrupt module handler function is called.
Returns
* CY_AS_ERROR_SUCCESS - the interrupt module was initialized
* correctly
* CY_AS_ERROR_ALREADY_RUNNING - the interrupt module was already
* started
See Also
* CyAsIntrStop
* CyAsServiceInterrupt

/* Summary
Stop the interrupt manager module
Description
This function stops the interrupt module and masks all interrupts
from the West Bridge device.
Returns
* CY_AS_ERROR_SUCCESS - the interrupt module was stopped
* sucessfully
* CY_AS_ERROR_NOT_RUNNING - the interrupt module was not
* running

* CyAsIntrStart
* CyAsServiceInterrupt

/* Summary
The interrupt service routine for West Bridge
Description
When an interrupt is detected, this function is called to
service the West Bridge interrupt. It is safe and efficient
for this function to be called when no West Bridge interrupt
has occurred. This function will determine it is not an West
Bridge interrupt quickly and return.
