PCI is Transaction/Burst oriented

PCI is a 32-bits bus, and so has 32 lines to transmit data. At the beginning of a transaction, the bus is used to specify a 32-bits address. Once the address is specified, many data cycles can go through. The address is not re-transmitted but is auto-incremented at each data cycle.
