Abstract
A microprocessor with a built-in instruction ROM is described. Arbitrary data is set in advance in a data register of the microprocessor. The arbitrary data is given to a program counter by a register indirect jump instruction. The microprocessor has a normal reset function and an additional reset function allowing reset from a predetermined address. The additional reset function is used when the logic level of a control signal input terminal is at a predetermined level when the reset signal to the reset terminal is cleared. The arbitrary data is transferred to the program counter by register indirect jump instruction and set in the program counter. The program is re-executed with this data as an instruction start address.
