ABSTRACT:
A microcomputer includes a program memory storing a string of instructions for a program, a central processing unit executing each instruction read out from the program memory, an instruction memory having an address area different from the program memory, a serial communication unit responding to data supplied in series thereto and writing instructions into the instruction memory in synchronism with an operation of the central processing unit, and an interrupt control unit responding to an interrupt request to cause the central processing unit to suspend the execution of the program stored in the program memory and to then execute instructions read out from the instruction memory to output internal conditions.
