The parallel subsystem is comprised of several functional blocks: a PCI bus master interface, a micromachine processing unit and its corresponding microcode ROM, and a PCI Target Control/Flash/EEPROM interface. The parallel subsystem also interfaces to the FIFO subsystem, passing data (such as transmit, receive, and configuration data) and command and status parameters between these two blocks.The PCI bus master interface provides a complete glueless interface to a PCI bus and is compliant with the PCI Bus Specification, Revision 2.2. The 82551IT provides 32 bits of addressing and data, as well as the PCI control interface. As a PCI target, it conforms to the PCI configuration scheme, which allows all accesses to the 82551IT to be automatically mapped into free memory and I/O space upon initialization of a PCI system. When transmit and receive data is processed, the 82551IT operates as a master on the PCI bus, initiating zero wait state transfers.The 82551IT Control/Status Register Block is part of the PCI target element. The Control/Status Register block consists of the following 82551IT internal control registers: System Control Block (SCB), PORT, Flash Control, EEPROM Control, and Management Data Interface (MDI) Control.An embedded micromachine consisting of independent transmit and receive processing units allow the 82551IT to execute commands and receive incoming frames with no real time CPU intervention
