ABSTRACT:
Consistent with one example embodiment, communications systems, using a serial data transfer bus having a serial data line and a clock line used to implement a communications protocol, incorporate programmable updating of slave device output banks sequentially or simultaneously. The communications system includes two or more slave devices and/or a slave device having two or more banks of output drivers. Each slave device receives serial data and provides a data word assembled from the serial data. A programmable register in each slave device is programmed, using the communications protocol, to select one or more slave device configurations. Each of the two or more slave devices and/or two or more banks of output drivers updates either sequentially, or in coordination with other of the two or more slave devices and/or two or more banks of output drivers, based on each slave devices configuration selected by its programmable register.
