Abstract
A circuit for controlling a receiver in an implanted device and circuitry for decoding and storing received program signals is disclosed. In the circuit a control circuit periodically activates a receiver to surveil for remotely generating programming signals. When a program signal is detected by the receiver the control circuit latches the receiver into a continuously activated state for a predetermined time interval. If a reset code is detected from subsequently received signals the receiver is held in an activated condition for a further predetermined time interval. Decoding circuits including a timer are reset upon receipt of the refresh code and provide control over sequences of received programming data for use in programming the stimulation mode of output circuits in the implanted device.
