A new digital configurable macro architecture is described. The digital configurable macro architecture is well suited for microcontroller or controller designs. In particular, the foundation of the digital configurable macro architecture is a programmable digital circuit block. The programmable digital circuit blocks can be configured to coupled in series or in parallel to handle more complex digital functions. More importantly, the configuration of the programmable digital circuit block is determined by its small number of configuration registers. This provides much flexibility. In particular, the configuration of the programmable digital circuit block is fast and easy since changes in configuration are accomplished by changing the contents of the configuration registers, whereas the contents are generally a small number of configuration data bits. Thus, the programmable digital circuit block is dynamically configurable from one predetermined digital function to another predetermined digital function for real-time processing.
