Abstract

PURPOSE:To effectively use this memory for the sound volume control for a TV receiver, by providing the non-volatile memory and presettable reversible counter so that the data before the interruption can be obtained as output when the power supply is reapplied. CONSTITUTION:The presettable reversible counter 11 and semiconductor non- volatile memory (M-NOS memory) 20 having the same number of bits are provided. Further, the output of the chattering prevention circuits 6, 7 is connected to the up down input terminal up, down of the counter 11 through the AND circuits 9, 10 together with the output of the oscillation circuit 1. Further, the switch 22 in interlocking with the power supply switch is connected to the pulse generating circuit 23, which produces the preset pulse presetting the data at the read-out terminals 01, 02, 03...0n of the memory 20 to the counter 11 after each power supply is stable and is connected to the preset terminal P0 of the counter 11.
