Abstract
Embodiments described herein provide SPI systems that can accommodate more peripheral devices on a serial data signal line. The present disclosure relates to various configurations of SPI communication interfaces that operably connect one or more peripheral devices serially to a controller device. The configurations of serially-connected peripheral devices can enable more peripheral devices to be supported on a serial data signal line in each SPI system. The present disclosure reduces or eliminates the limitation regarding the driving capability of the controller device or the peripheral devices. The present disclosure further reduces the restriction regarding the pin count requirement for the select signals.
