10.3 EXAMPLES OF BUS TIMING FOR LOCAL BUS PCI BRIDGE MODE
OPERATION
Figure 10.3A
8-Bit Read Cycle
Intel Mode (LIM = 0)
Arbitration Enabled (LARBE = 1)
Bus Transaction Time = 4 LCLK (LRDY = 0100)
An attempted access by the Host causes the Local Bus to request the bus. If bus access has not been
granted (LBGACK* deasserted), then the timing shown at the top of the page will occur with LHOLD
being asserted and then once LHLDA is detected, the Local Bus will grab the bus for 32 to 1048576
clocks and then release it. If the bus has already been granted (LBGACK* asserted), then the timing
shown at the bottom of the page will occur.
