ABSTRACT:
A circuit for use in programmable hearing aids is programmed by inputting digital pulses along two input lines. The programmed information is stored in ring counters and then registered in EEPROMS. A multiplexer (itself a ring counter) selects the ring counter which will be incremented by pulses input to one of the input lines.
