Timer 3 Modulator for Carrier Frequency Burst Modulation
Timer 3 Demodulator for Biphase, Manchester and Pulse-width-modulated Signals
ATAM862-4
If the output stage operates as pulse-width modulator for the shift register, the output can be
stopped with stage 1 of Timer 2. For this task, the timer mode 3 must be used and the prescaler
must be supplied by the internal shift clock of the shift register.
The modulator can be started with the start of the shift register (SIR = 0) and stopped either by a
shift register stop (SIR = 1) or compare match event of stage 1 of Timer 2. For this task, the
Timer 2 must be used in mode 3 and the prescaler stage must be supplied by the internal shift
clock of the shift register.
Figure 23-13. Modulator 3
The demodulator stage of Timer 3 can be used to decode Biphase, Manchester and
pulse-width-coded signals.
