Transmission diagnosis
The transmission compares RxD1 and RxD2 inputs (through the input comparators and the filters) with the data
transmitted on TxD output.
At a time when the transmission logic generates a dominant - recessive transition, the inputs can give different
values. Taking into account the filtering delay, the bus line seen as dominant is assumed to be correct, the other one,
recessive, is considered faulty. The diagnosis mode is changed to reflect that.
Protocol fault
The protocol fault is detected by counting the number of consecutive dominant timeslots.
If eight consecutive timeslots are dominant, the diagnosis mode will change to the major error mode.
8.3. Generation of Internal Signals
8.3.1. RI Signal (Return to Idle)
This signal is used to return to nominal mode in the three specified selection modes (see sections 8.1. and 8.4.). The
RI signal is disabled in automatic selection mode.
The RI signal is a pulse generated when an EOF is detected. So, at the end of each frame, the user, regarding the
diagnosis status bit Sa, Sb & Sc, can make its own choice.
8.3.2. SDC Signal (Synchronous Diagnosis Clock)
This time base is used by diagnosis system in automatic selection mode (see section 8.4. ) when no event is recorded
on the bus.
The SDC is generated either by a special SDC divider connected to the timeslot clock, either manually. The SDC clock
period must be long compared to the timeslot duration.
A typical SDC period should be greater than the maximum frame length appearing on the VAN network.
8.3.3. TIP Signal (Transmission In Progress)
This signal must be enabled to allow the transmission diagnosis (see section 8.2.2.).
The TIP turns on synchronously with the beginning of the transmission:
for asynchronous bus access, the beginning of SOF,
for synchronous bus access, the beginning of the identifier field,
for a requestee of in frame reply, the RTR bit of the command field.
The TIP turns off synchronously with the end of the transmission:
after EOF
after a losing of arbitration or a code violation detection
for a requestor of in frame reply, when the arbitration is lost on RTR the bit.
This signal is not generated when the transmission logic only sends an ACK.
