PROBLEM TO BE SOLVED: To provide a system which can reduce a loss of a setting time for a register.SOLUTION: An integrated circuit device has plural interface controllers which control transfer of data between an external main controller and plural devices respectively. Each of the plural interface controllers has at least one register. The integrated circuit device comprises: an internal memory in which a setting value to be set to a register group including at least one register of the plural interface controllers is stored; a register controller which upon detection of an event, updates a value of a register associated with the detected event in the register group to a setting value associated with the detected event; and a dedicated bus in which the register controller supplies setting values to respective registers of the register group in parallel. |
