4708D–4BMCU–09/05
Combination Mode 5: Bi-phase Modulation 2
SSI mode 1:
Timer 2 mode 3:
Timer 2 output mode 4:
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 via the shift-clock. The control output signal
(OMSK) of the SSI is used as a stop signal for the modulator.
