Registers
MXLA (Maximum Latency): This is a read-only register from the PCI/X configuration
space, and may be written at any time from within the Combined Register Group. The MXLA
register specifies how often access to the PCI/X bus is required. The value is presented in
units of 0.25 us. This register defaults 0x00 following the release of reset which indicates that
there are no particular latency requirements.
MNGN (Minimum Grant): This is a read-only register from the PCI/X configuration space,
and may be written at any time from within the Combined Register Group. The MNGN
register specifies how long of a burst period is required. The value is presented in units of 0.25
us. This register defaults to 0x00 following the release of reset which indicates that there are
no particular grant requirements.
