Abstract

PURPOSE: To improve a test processing function by providing hardware, which supplies clock by itself, to a clock unit supplying selectively normal clocks, and margin clocks.
CONSTITUTION: Clock counter 6 counts upby a clock supplied to processing part 1 and generates a timing signal as soon as its contents reaches a value preset by the indication from service processor 3. Input control register 7 indicates the mode of mode selector circuit 8 and its contents are preset by service processor 3. Mode selector circuit 8 selects the 1st mode in which service processor 3 controls direct clock unit 2 or the 2nd mode in which it controls the unit by the timing signal from clock counter 6.
