Timer 2 Output Mode 1
The signal at the timer output is generated via modulator 2. In the toggle mode, the compare
match event toggles the output T2O. For high resolution duty cycle modulation 8 bits or 12 bits
can be used to toggle the output. In the duty cycle burst modulator modes the DCG output is
connected to T2O and switched on and off either by the toggle flip-flop output or the serial data
line of the SSI. Modulator 2 also has two modes to output the content of the serial interface as
Biphase or Manchester code.
The modulator output stage can be configured by the output control bits in the T2M2 register.
The modulator is started with the start of the shift register (SIR = 0) and stopped either by carry-
ing out a shift register stop (SIR = 1) or compare match event of stage 1 (CM1) of Timer 2. For
this task, Timer 2 mode 3 must be used and the prescaler has to be supplied with the internal
shift clock (SCL).
