摘要

An electronic timepiece including a ROM program memory for storing a program, a program counter for addressing the program memory, and a RAM data memory. An operating circuit including an arithmetic logic circuit operates on the data. The ROM program memory circuit stores a test program, and the program counter includes preset test means for addressing the test program stored in the ROM program circuit to operate the timepiece according to the test program. The program memory counter also includes jump inhibiting means for inhibiting execution of the operating program stored in the ROM program memory, in response to a jump address.
