CHAPTER 2 OVERVIEW OF PCI HOST BRIDGE MACRO
The PCI host bridge macro enables connection of V850E/MA1, V850E/MA2, V850E/MA3, V850E/ME2 external
bus interfaces to the PCI bus interface. This chapter gives an outline of the PCI host bridge macro.
2.1 Outline
The PCI host bridge macro is a bridge control macro that connects V850E/MA1, V850E/MA2, V850E/MA3,
V850E/ME2 external bus interfaces (memory controller (MEMC)) to the PCI bus interface.
The main memory (SDRAM) can be directly controlled when SDRAM is accessed from a PCI device.
