8-Bit Control-Oriented Microcontrollers
The MCS-51 controllers are optimized for control applications. Byte-processing and numerical
operations on small data structures are facilitated by a variety of fast addressing modes for accessing
the internal RAM. The instruction set provides a convenient menu of 8-bit arithmetic instructions,
including multiply and divide instructions. Extensive on-chip support is provided for one-bit variables
as a separate data type, allowing direct bit manipulation and testing in control and logic systems that
require Boolean Processing.
