MB90F456 Overview
MB90455 series devices are general-purpose high-performance 16-bit micro controllers designed for process control of consumer products, which require high-speed real-time processing. The system, inheriting the architecture of F2MC family, employs additional instruction ready for high-level languages, expanded addressing mode, enhanced multiply-divide instructions, and enriched bit-processing instructions....
