Combination Mode 4: Manchester Modulation 2
SSI mode 1:
Timer 2 mode 3:
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. This is an example for a 12-bit

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. This is an example for a 13-bit Bi-
phase telegram.
