CAN Controller Interrupts

Each CAN controller is tied to a local interrupt on the PLX9030 which is then forwarded to a single interrupt
on the PCI bus. Access to the PLX9030 interrupt control/status register can be done by accessing the
INTCSR register at offset 4Ch from the PCI base address of the CANpro/104-Plus Opto.
This diagram is taken from the PLX9030 Data Book v1.4.
