ATAM893-D
Combination Mode 4: Manchester Modulation 2
SSI mode 1:
8-bit shift register internal data output (SO) to the Timer 2
modulator stage
Timer 2 mode 3:
8-bit compare counter and 4-bit prescaler
Timer 2 output mode 5:
The modulator 2 of Timer 2 modulates the SSI data output to
Manchester code
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:
8-bit shift register internal data output (SO) to the Timer 2
modulator stage
Timer 2 mode 3:
8-bit compare counter and 4-bit prescaler
Timer 2 output mode 4:
The modulator 2 of Timer 2 modulates the SSI data output
to Bi-phase code
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.
