A semiconductor integrated circuit device includes a memory storing a microprogram used for controlling a desired function, a generator for generating an internal microprogram activating signal. A switching part selects either one of an external microprogram activating signal generated by an external device and the internal microprogram activating signal generated by the generator based on a first signal supplied from outside of the semiconductor integrated circuit device, thereby outputting a selected microprogram activating signal. A microaddress generator generates a microaddress of the microprogram stored in the memory. The microaddress generator is activated by the selected microprogram activating signal.
A semiconductor integrated circuit device, comprising:
A semiconductor integrated circuit device as claimed 15, wherein said arbitrary microaddress is supplied, as said external input microaddress, to said memory means, so that the microprogram stored in said memory means is started from said arbitrary microaddress, and a corresponding microprogram read out of said arbitrary microaddress, is output outside of the semiconductor integrated circuit device, so that a desired text is made by monitoring said output microaddress.
A semiconductor integrated circuit device, which is a direct memory access controller used for controlling a data transfer by a direct memory access between devices coupled to a system bus to which the direct memory access controller is also coupled, said semiconductor integrated circuit device comprising:
