Abstract
A serial port controller in an embedded disk drive controller is provided. The serial port controller includes a state machine that can access protocol information regarding plural devices operationally coupled to the serial port controller; a first register that can hold address information of the plural devices; and logic for enabling the plural devices for either a write or read request. The serial port controller also includes a second register for holding write data information for the plural devices; and a third register for holding read data information for the plural devices. The serial port controller reads programmed information regarding the plural device upon a client request; transmits the address of a device with whom communication is requested by the client; and transmits data to the plural devices, if the request by the client is to write data or collects data for a read request.
