Abstract
Data throughput of the serial host interface is improved by combining command and register address data into a single index word to be transmitted through the serial host interface. The least significant bit (LSB) of the index word specifies the command and the remainder of the index word specifies the register address. Thus, transmission of just two words is required to transmit each of a single write data word and a single read data word. Additionally, the serial host interface provides for elimination of the dummy access word as required when performing a read transmission using a conventional serial host interface protocol.
