3.6 Handling PCI Controller Registers
The PCI bus controller adopted in PCI-7258 is the PCI-9030, which is
provided by PLX technology Inc. When users attempt to handle low-level
programming, some registers in the PCI-9030 should be noticed. The
interrupt control register (INTCSR; 0x4Ch) of the PCI-9030 takes charge of
all interrupt information from the local bus to PCI bus. When users want to
develop their own interrupt function driver, both interrupt registers in the PCI-
9030 and in PCI-7258 have to work together. For more information about the
interrupt control register in the PCI-9030, refer to the PCI-9030 data book.
With the PCI-7258 software function library, ADLINK has provided simple
and easy-to-use functions to handle the procedures of interrupts. Using these
functions, users are not required to know about the interrupt register in the
PCI controller. Hence, we recommend users use these functions instead of
developing your own interrupt functions. For more information about the PCI-
7258 function library, refer to Chapter 5.
