IrDA Control system uses 16PSM coding scheme over 1.5MHz sub-carrier. See IrDA Control Physical Layer Link Specification for the details of coding scheme and pulse characteristics. See Figure 5.1 (below) for the viewing angle definition. An in-band optical signal is a pulse/sequence where the peak wavelength p, is defined as 850nm < p < 900nm, and the pulse characteristics are compliant with the IrDA Control Physical Layer Link Specification.

10. 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:

RESET input > 13sec 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 > 13sec enables this function to work. This > 13sec 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.
