COMMUNICATION CONTROLLER AND METHOD

摘要

A communication control circuit (102, 103) comprises a shift register (121) and a control data selector (124) and controls a plurality of controlled units (127) according to a data signal (DAT), a clock signal (CLK), and a strobe signal (STB) which have been inputted via three serial signal lines. The shift register (121) applies serial-to-parallel conversion to the data signal (DAT) sequentially captured according to the clock signal (CLK) and outputs it. The control data selector (124) selects control data for controlling corresponding one of the controlled units (127) from the signals of the shift register (121) according to a device definition signal (CDEV) for identifying the communication control circuit (102, 103) and outputs it.
