22.2.4.8 Time Out

Once all data has been sent in addition to the optional bits, there should be a time-out on the SLO line while the host transmits the CDM bit. In BiSS time-out, no further clock pulses are sent to the MA by the host. The inverse state of the MA line during the BiSS time-out is the state of the CDM bit. At the end of the data transmission, the host sets its output MO to the Idle state ‘1’. The clients then pass on this ‘1’ received at SLI to their output SLO as soon as they have detected the expiration of the time-out. This ensures the BiSS time-out on the line SL is only signaled to the host when all connected clients have detected the time-out. When the BiSS time-out expires, all clients return to the Idle state; all lines are set to the high signal level (‘1’) in the process.”
