As can be seen from the transition criteria, combinations of multiple conditions are
possible as well. A “ ” stands for a logical AND combination. And a “+” indicates a logical
OR combination.
Test Signals
• 2 kHz Single Pulses (TM1)
• 96 kHz Continuous Pulses (TM2)
Note: The test signals TM1 and TM2 can be generated via pins TM0-2 according to
Reset States
After an active signal on the reset pin RST the S-transceiver state machine is in the reset
state.
C/I Codes in Reset State
In the reset state the C/I code 0000 (TIM) is issued. This state is entered after a hardware
reset (RST).
C/I Codes in Deactivated State
If the S-transceiver is in state ‘Deactivated‘ and receives i0, the C/I code 0000 (TIM) is
issued until expiration of the 8 ms timer. Otherwise, the C/I code 1111 (DI) is issued.
Data Sheet
One pulse with a width of one bit period per frame with alternating polarity.
Continuous pulses with a pulse width of one bit period.
