Abstract:
1. A communication timing changing method for changing timing of communication by setting control parameters, from a central processing unit (CPU), used to determine operation modes of analog devices, respectively, over to another operation mode corresponding to a period which does not impede any operations of said analog devices, said method comprising: generating a synchronous signal synchronized with the period not impeding any operations of said analog devices by a synchronous signal generating circuit included in an integrated circuit; transferring the control parameters used to determine the operation modes of said analog devices from said CPU to a register, included in the integrated circuit, during operation periods of said analog devices, except for the period which does not impede any operations of said analog devices, to store the control parameters in said register based on the synchronous signal generated by said synchronous signal generating circuit; and managing timing of communication, between said register and said analog devices, by setting the control parameters stored in said register in said analog devices, respectively, synchronously with the period which does not impede any operations of said analog devices by at least one interface encoder based only on the synchronous signal generated by said synchronous signal generating circuit, wherein setting the control parameters in said analog devices includes transferring and storing the control parameters in said analog devices, said analog devices being separate from the integrated circuit.
