Claim Text:
1. A semiconductor integrated circuit comprising: a plurality of input terminals; a plurality of output terminals; a plurality of flip-flop circuits; a memory circuit configured to store configuration information to configure connection relationship between said input terminals and said flip-flop circuits and connection relationship between said output terminals and said flip-flop circuits; a first selector circuit configured to switch connection between said input terminals and said flip-flop circuits based on said configuration information from said memory circuit; a second selector circuit configured to switch connection between said output terminals and said flip-flop circuits based on said configuration information from said memory circuit; a third selector circuit configured to select an output of said flip-flop; and a counter circuit configured to receive said selected output from said third selector, count a number of toggle times of said output of said flip-flop circuits, and output the count value to a control device.
