19 / 39 page  AN4099 Infrared receiver Doc ID 023110 Rev 2 19/39 The timer generates three types of interrupt. ● Interrupt at each falling edge: this can be used to measure the entire pulse (duration between two successive falling edges). ● Interrupt at each rising edge: this can be used to measure the low pulse (duration between falling and rising edges). ● Update event: this is used to put the infrared packet into default state (bit count, data and status) when the timer counter overflows. The low pulse and whole pulse duration are used to determine the bit value. If the durations are within the tolerance range of the bit time, one identifies the bit value (Logic0, Logic1 or Header). The flowchart below gives an overview of the infrared decoding procedure. Figure 16.
