This bridge chip enables SPARClite (host CPU) access in program mode (direct master operation) to devices on a PCI bus. Also, the SPARClite host can invoke the built-in DMA function on the bridge chip to allow access to devices on the PCI bus. Access from the PCI side to devices on the SPARClite bus (SL bus) is enabled by using the bridge chip slave operation function. The DMA function can be...
