Local Bus Controller

This chapter describes the local bus controller (LBC) block. It describes the external signals and the

memory-mapped registers as well as a functional description of the general-purpose chip-select machine

(GPCM), SDRAM machine, and user-programmable machines (UPMs) of the LBC. Finally, it includes an

initialization and applications information section with many specific examples of its use.
