Combination Mode 5:
Biphase Modulation 2
4554A–4BMCU–02/03
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 mod-
ulator 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 stop signal for the modulator.
Figure 73 shows an example for a 13-bit Biphase telegram.
