“Note;
By setting signals ST[3:0] to the following value allows the STPC to be put
Tristate. This means the STPC is switched off and no signals are being driven. “

“The DRAM controller to execute the host transactions is also driven by this
clock”

“AD[31:0] PCI Address/Data. This is the 32-bit multiplexed address and data
bus of the PCI. This bus is driven by the master during the address phase and
data phase of write transactions. It is driven by the target during data phase of
read transactions.”

“IDE devices are connected to SA[19:8] directly and ISA bus is connected to
these pins through two LS245 transceivers. The OE of the transceivers are
connected to ISAOE
nals of the transceivers are connected to CPC and IDE DD bus and the B bus
signals are connected to ISA SA bus .”

“For IDE devices, these signals are used as the DA[2:0] and are connected to
DA[2:0] of IDE devices directly or through a buffer . If the toggling of signalsis to
be masked during ISA bus cycles, they can be externally ORed before being
connected to the IDE devices.”
