This register may be optionally used by bus masters to
specify how often this device needs PCI bus access. A
value of zero indicates that the bus master has no
stringent requirement. The units defined by the least
significant bit are in 250 ns increments. Since the
S5920 is a PCI target device only, this register is
treated as “information only” and has no further imple-
mentation within this device.
