Consistent with one example embodiment, communications systems (100,300), 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 (350,360). Each slave device receives serial data and provides a data word assembled from the serial data. A programmable register (380) 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 progammable register.
(ZH) 根据一个示例性实施例，使用用于实现通信协议的、具有串行数据线和时钟线的串行数据传送总线的通信系统(100，300)，包括相继地或同时对从设备的输出组进行可编程更新。该通信系统包括两个或更多个从设备，和/或具有两个或更多个输出驱动器组(350，360)的从设备。每个从设备接收串行数据，并提供由该串行数据组合的数据字。使用通信协议对每个从设备中的可编程寄存器(380)进行编程，以选择一个或更多个从设备配置。两个或更多个从设备和/或两个或更多个输出驱动器组中的每一个，根据其可编程寄存器所选择的每个从设备配置，相继地或与两个或更多个从设备和/或两个或更多个输出驱动器组中的其他协同地进行更新。
