PURPOSE:To enable the alteration of many functions by switching timepiece functions in an IC utilizing an EPROM. CONSTITUTION:Terminals 3-5 are set to the level H or L depending on the contents written into an EPROM1 from a terminal 2 and according to the set condition, a decoder section 14 operates to output a hand running pulse with the set width by one sec from a terminal 13. A larger number of pulse widths can be set by increasing the number of bits in the EPROM1 and the pulse width itself can be made freely by altering the circuit of the decoder section 14. |
