SOLUTION

• The PCI BUS supports I/O, Memory and Configuration address space/s.
• The bus transactions to memory, I/O, and configuration address spaces imply that the PCI bus master accesses data within a target by providing a specific address.
• These bus transactions are memory read and write, I/O read and write, and configuration read and write.
• The term “memory mad transactions” relative to PCI includes memory read, Memory Read Multiple (MRM).
• The PCI BUS is mainly built to provide a wide range of connectivity for devices.
