Revision 1.01
The W89C840AF uses only one interrupt pin, INTA#. However, the interrupt line resource assignment
is determined by the system BIOS by writing the related data into the bits 0 to 7 of the register F3C/FIR in the
W89C840AF. The data written into the bits0 to 7 of the register F3C/FIR can be used by the driver program to
decide the interrupt service subroutine configuring.
PCI Configuration register
The general attributes of the PCI configuration registers implemented in the W89C840AF are described as
the following:
1) Writes to the reserved configuration registers are treated as no-op. The bus access will complete without
affecting any data in the W89C840AF internal registers.
2) Read from the reserved or un-implemented registers will be returned 0
value.
3) S/W reset (C00<0> ) has no effect on the PCI configuration registers.
4) H/W reset will clear the PCI configuration registers.
5) The implemented configuration registers support any byte enable combination access.
6) Burst access to the configuration registers will be terminated after 1st data transfer completed with a with
a disconnect without data.
The following table outlined all the PCI configuration registers inside this chip and summarized its function.
