摘要: A microcomputer for emulation which has been conventionally unusable when built-in RAM capacities are different, because an access to an internal function circuit is different in bus control, wait condition and the like from the access to an external memory area, and despite the above fact, which now becomes usable by including a built-in RAM 17, a higher address decoder (virtual RAM address decoder) for generating a virtual RAM address space corresponding to a plurality of virtual RAM capacities within a range in which installed capacity of the built-in RAM 17 is made a maximum value, and a RAM capacity selection flag 36 for specifying any one of a plurality of virtual RAM address spaces which can be generated by the higher address decoder 22.

摘要: There is a need to cause a delay to occur less frequently than the related art during processing of an input signal in need of relatively fast processing. In a semiconductor device, a conversion portion includes first channels and second channels and A/D converts a signal input to a selected channel. A signal input to the first channel requires faster processing than a signal input to the second channel. The conversion portion receives a scan conversion instruction from a central processing unit, sequentially selects the input channels in a specified selection order, and successively performs A/D conversion. In this case, the conversion portion notifies a peripheral circuit of completion of A/D conversion after completion of A/D conversion on signals input to the first channels and before completion of A/D conversion on input signals input to all input channels.
