Abstract
A microcontroller is provided with a plurality of slave drive units for driving peripheral devices. Individual speed units are provided that have serial shift registers, multiplexors, and duplex data communication connections with individual serial registers of respective slave drive units of a series chain. In a first cycle or mode, a serial data connection between the serial shift registers of the speed units causes data to be serially communicated, at a first relatively faster pulse rate, from the microcontroller into the data input of the series chain and to the microcontroller from the data output of the series chain. In a second cycle or mode, for each pair of single speed unit and slave drive unit, the duplex data communication between the serial shift registers of the pair causes, at a second relatively slower pulse rate, data to be serially communicated in parallel therebetween.
