1.4.3 PCI Bus Bridge Module
The PCI bus bridge module (PBM) is a single-slot PCI long card module that interfaces
between the 32-bit PCI bus and the interconnect cable that links the bus to the VMEbus
bridge module (VBM). The PBM, which adheres to PCI Local Bus Version 2.1 Specification,
contains the control logic and data buffering to perform this data link.
