An Infrared (IR) receiver includes a programmable decoder having a normal mode of operation and a proprietary mode of operation. When the programmable decoder is in the normal mode of operation, the programmable decoder decodes frames of an IR data transmission to produce decoded data. When the programmable decoder is in the proprietary mode of operation, the programmable decoder passes data of the IR data transmission during a time out period to produce raw data. The IR receiver also includes a pulse detection circuit that generates a pulse detection signal in response to detecting the IR data transmission. The IR receiver further includes a timer circuit that generates the timeout period in response to the pulse detection signal.
