Timer 2 output mode 5:
The 4-bit stage can be used as prescaler for the SSI to generate the stop signal for modulator 2.
The SSI has a special mode to supply the prescaler with the shift clock. The control output signal
(OMSK) of the SSI is used as stop signal for the modulator.
12-bit Manchester telegram.
