Abstract
In an LSI for an electronic watch having a ROM and a RAM, the content of the RAM is rewritten by the interpretation and execution sequentially for time counting control and other controls. The address designation method of the ROM comprises a Program Counter Method for designating the next instruction address to be executed by a program counter and for numerical computation, and a Next Address Designation Method for designating directly by a fixed field value in an instruction and for the software for the watch. The two methods are employed selectively by the kind of instructions so that an emit-field may be used for other purposes such as the operation of a value which extends over several words of the RAM as a single instruction.
