<p>A semiconductor integrated circuit device includes a memory (3, 43) storing a microprogram used for controlling a desired function, a generator (23) for generating an internal microprogram activating signal (TFLGX, OREQX). The semiconductor integrated circuit device also includes a switching part (1) for selecting either one of an external microprogram activating signal (ETFLGX, EOREQX) generated by an external device and the internal microprogram activating signal generated by the generator on the basis of a first signal supplied from the outside of the semiconductor integrated circuit device, thereby outputting a selected microprogram activating signal. The semiconductor integrated circuit device further includes a microaddress generator (2) for generating a microaddress of the microprogram stored in the memory, the microaddress generator being activated by the selected microprogram activating signal.</p> |
