RESET Function The “RESET” terminal is used to recover the receiver sensitivity to its maximum level. Since Sharp IrDA Control Infrared Transceiver has a built-in capability to adjust the receiving sensitivity, as a result, a very weak IR signals may not be correctly received just after receiving a very strong IR signals. Following figure shows an example of “RESET” signal in order to recover the Sharp IrDA Control Infrared Transceiver’s receiving sensitivity to its receiving sensitivity to its maximum level: AGCN Optical Signal Gap Time Vo RESET input > 13µsec tret: The time period until AGCN tret (NOTES) This pinout is an Active Low terminal, and stays HIGH level when it is OPEN. The Low Level Pulse for the period of > 13µsec enables this function to work. This > 13µsec input must be pulsed within the period of Gap time in order for the transceiver to have receiver sensitivity recovery. The timing for this “RESET” pulse should be adjusted at controller side. 11.
