ABSTRACT:
A management unit for microcontrollers equipped with a decoder for a plurality of interrupt channels, the unit being connected to a central processing unit of the microcontroller to decode and transfer thereto a single interrupt digital signal through the decoder, and comprises a first circuit portion for selecting homolog pairs of channels incorporating a modular chain of elements, each having a respective channel pair connected thereto. The first or selection portion is associated with a second decoding circuit portion, and the interrupt signal is a reform of the channel interrupt vector carrying higher priority in the channel pair selected by the chain.
