FW322 Vendor-Specific Registers
The FW322 contains a number of vendor-defined registers used for diagnostics and control low-level hardware
functions. These registers are addressable in the upper 2K of the 4K region defined by PCI base address
register 0 (registers defined by the OHCI specification reside in the lower 2K of this region). The control registers
should not be changed when the link is enabled.

Register Name
IsoDMACtrl
Description
Controls PCI access for the isochronous DMA contents. Initial values
are loaded from serial EEPROM, if present.
Controls PCI access and AT FIFO threshold for the asynchronous
DMA contexts. Initial values are loaded from serial EEPROM, if
present.
Controls low-level functionality of the link core. Initial values are loaded
from serial EEPROM, if present.
