Abstract
A time data processing circuit for an electronic timepiece comprises a common line; a signal generator for generating time data signal and first, second, third and fourth control signals; first and second shift register circuits; an arithmetic operation circuit for processing the time data signal and the output signal of the first shift register circuit; a first input/output circuit for coupling, in response to the first control signal, the output terminal of the arithmetic operation circuit to the common line and the input terminal of the first shift register circuit and coupling, in response to the second control signal, the common line to the input terminal of the first shift register circuit; and a second input/output circuit for coupling, in response to the third control signal, the output terminal of the second shift register circuit to the input terminal of the second shift register circuit and the common line and coupling, in response to the fourth control signal, the input terminal of the second shift register circuit to the common line.
