Abstract
A microprocessor on-board RAM provides both the usual random access by addressing and a subset of memory cells with their contents continually available on a secondary bus paralleling the data bus. This secondary bus may be used for register indirect addressing without a separate register read when the RAM subset includes the registers for register indirect addressing. The processor also has a two stage output driver for limiting maximum output current and feedback-controlled clock period partitioning.
