PURPOSE:To enable a delicate inspection to be conducted by providing a counter to count the number of clock pulses. CONSTITUTION:When signals from a terminal TEST are at an 'H' level, T-FF2-4 upcount the number of the clock pulses of signals from a terminal TMODE and feed the binary numerals of LSB and MSB to a test control block C. The block C feeds out a signal group for changing over switches in a function block group G in response to input signals to the block C. Thus, the inspection of the block group G is perfectly conducted.
