Timer 3 – Mode 11: Biphase Demodulation
Timer 3 – Mode 12: Timer/Counter with External Capture Mode (T3I)
In the Biphase demodulation mode, the timer operates like in Manchester demodulation mode.
The difference is that the bits are decoded via a toggle flip-flop. This flip-flop samples the edge in
the middle of the bitframe and the compare register 1 match event shifts the toggle flip-flop out-
put into shift register (see
Figure 23-11. Biphase Demodulation
The counter is driven by an internal clock source and an edge at the external input T3I loads the
counter value into the capture register. The edge can be selected with the programmable edge
detector of the timer input stage. This mode can be used for signal and pulse measurements.
