Table 5-156: PT_FAIIntScanStart Member Description
Note
The IntrCount value for PCL-818HD and PCL818HG can be set to 1
or FIFO_SIZE(512), the IntrCount value for PCL-1800 is varied
(>=1). But the IntrCount value for other cards which has no FIFO on
board should be set to 1 only.
The IntrCount value for PCI-1710 can be set to 1 or
FIFO_SIZE(2048), the IntrCount value for PCI-1710 is varied
(>=1). But the IntrCount value for other cards which has no FIFO on
board should be set to 1 only.
