PROBLEM TO BE SOLVED: To provide a system controller and a system controlling method which stably and surely cancels resetting of a system, prevents initial malfunction of the system due to an unlocked abnormal clock, and starts the system operation normally. SOLUTION: A PLL means P1 goes into a lock state, and a clock signal (g) from the PLL means P1 is stabilized sufficiently for detecting the lock state by a lock detector 107. Then the reset state of a system under control with a reset signal (j) from a reset output unit 108 is released, to start the operation of various functional blocks of the system. |
