PURPOSE:To enable the characteristic test of a register file to be easy and positive. CONSTITUTION:Master latch groups 1-4 latch either the normal input signal from input terminals 10-13 and the input signal for testing from input terminals 16-19 according to the test instruction signal from an input terminal 20. A selector 9 outputs either the output signal for testing from the master latch groups 1-4 or the output signal for testing from a slave latch group 8 according to the test output selection signal from an input terminal 21. |
