Description

Latency Timer
This value specifies the latency timer of the AN983B/BX in units of PCI
bus clock. Once the AN983B/BX asserts FRAME#, the latency timer
starts to count. If the latency timer expires and the AN983B/BX still
asserted FRAME#, then the AN983B/BX will terminate the data
transaction as soon as its GNT# is removed.
Cache Line Size
This value specifies the system cache line size in units of 32-bit double
words (DW). The AN983B/BX supports 8, 16, and 32 DW of cache line
size. This value is used by the AN983B/BX driver to program the cache
alignment bits (bit 14 and 15 of CSR0). The cache alignment bits are used
for cache oriented PCI commands; say memory-read-line, memory-read-
multiple, and memory-write-and-invalidate.
Description
I/O Base Address
This value indicates the base address of PCI control and status register
(CSR0~28).
