8. TIMING DIAGRAMS
The PCI 9080 operates in three modes, selected through mode pins, corresponding to three bus types—C, J, and S.
Timing Diagrams are provided for the three operating modes. For some functions, a timing diagram may only be provided
for one mode of operation. Even though a different mode is used, the timing diagram can be used to determine
functionality.
