Min. Grant (3Eh) and Max. Latency (3Fh) Registers
These read-only registers specify the desired latency timer value. They each represent a number of 1/4 microsecond time

The Min Grant is the time required to complete a worst case burst assuming a 33MHz PCI clock. The hard coded value is
02h which represents 0.5µs.
The Max Latency specifies how often the W83C554F needs to gain control of the PCI bus. The hard coded value is 28h
which represents 10µs.
