Abstract
An electronic timepiece having multi-functions comprises a quartz oscillation circuit as a time standard signal generating circuit, a dividing circuit for dividing the output signal of said quartz oscillation circuit, a timing pulse generating circuit for generating a timing pulse signal which operates many kinds of circuit blocks as an input signal of one part of the output of said dividing circuit, a ROM-circuit as a program memory for executing multi-function operations of the timepiece and others, a program counter and page counter for renewing an address of said ROM-circuit, a RAM-circuit as a data-memory for memorizing a controlling memory, an operated result and a time information, an operation circuit for executing many kinds of operations, a data comparison and a data transformation, a latch circuit as an output data memory circuit for temporarily memorizing a display data or other necessary output data, a driver circuit for displaying all of or a part of the contents of said latch circuit, an alarm sound combining circuit in which a part of the output signal of said dividing circuit can be applied thereto, and wherein at least a part of the address of said program memory is synchronously driven by a 100 HZ signal.
