ADLINK PCI-7256 - Manual (Page 31)

Register Format • 23
In PCI-7256 software funciton library, we provide simple and easy-to-use
functions to handle the procedure of interrupt. Using these functions, users
don’t need to care about the interrupt register in PCI controller. We suggest
users use these functions instead of developing interrupt functions by
themselves. For more information about PCI-7256 funciton library, please
refer to Chapter 5.
