Cache Line Size
This register specifies the system cache line size in units
of 32-bit words. In the conventional PCI mode, the
LSISAS1064 PCI function uses this register to determine
whether to use Write and Invalidate or Write commands
for performing write cycles. Programming this register to
a number other than a nonzero power of two disables the
the use of the PCI performance commands to execute
data transfers. The PCI function ignores this register
when operating in the PCI-X mode.

Latency Timer
The Latency Timer register specifies, in units of PCI bus
clocks, the value of the Latency Timer for this PCI bus
master. If the LSISAS1064 initializes in the PCI mode, the
default value of this register is 0x00. If the LSISAS1064
initializes in the PCI-X mode, the default value of this reg-
ister is 0x40.
