R
MAXLAT
Max Latency Timer
Loaded from EEPROM. Indicates how often, in units of 0.25
μ
S, W89C841F needs to gain
access to PCI bus. Assuming
PCI clock rate is 33 MHz.

R
MINGNT
Min Grant Timer
Loaded from EEPROM. Indicates how long a burst period,
in units of 0.25
μ
S, is needed by W89C841F. Assuming PCI
clock rate is 33 MHz.
15:8
R
IPIN
Interrupt Pin
Fixed at 01h. Indicates INTAB is used.
7:0
