Title
(EN) I2C slave device with programmable write-transaction cycles
(ZH) 具有可编程写事务周期的I2C从设备
Abstract
(EN) 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.
