Functional Description
(Continued)
3.5.2 ISA Bus Interface
The ISA bus controller issues multiple ISA cycles to sat-
isfy PCI transactions that are larger than 16 bits. A full 32-
bit read or write results in two 16-bit ISA transactions or
four 8-bit ISA transactions. The ISA controller gathers the
data from multiple ISA read cycles and returns TRDY#
only after all of the data can be presented to the PCI bus
at the same time.
SA[23:0] are a concatenation of ISA LA[23:17] and
SA[19:0] and perform equivalent functionality at a reduced
pin count.
Figure 3-8 shows the relationship between a PCI cycle
and the corresponding ISA cycle generated.
