Figure 41. Remote sensor synchronization pulses

L9680 supports three time slots in a sync period with associated RSDRx registers. The

messages received within one sync period are routed to the corresponding RSDRx register

associated to each time slot. A time slot control is performed to check if the incoming

messages fall within the valid time slots reported in Table 62 and sketched in Figure 42 If

the end of the received message occurs after the end of the checked outside a valid time

slot, a SLOT_ERROR fault will be detected and stored in the related RSDRx register. If two

messages end within the same slot, the second message will be assigned to that slot,

regardless its validity. The time slot control can be disabled by setting the TSxDIS bit in the

RSCRx register.
