Bit Timing
Figure 16-6. Listening Mode
FSM’s (Finite State Machine) of the CAN channel need to be synchronous to the time quan-
tum. So, the input clock for bit timing is the clock used into CAN channel FSM’s.
Field and segment abbreviations:
The total number of TQ in a bit time has to be programmed at least from 8 to 25.
Figure 16-7. Sample and Transmission Point
• BRP: Baud Rate Prescaler.
• TQ: Time Quantum (output of Baud Rate Prescaler).
• SYNS: SYNchronization Segment is 1 TQ long.
• PRS: PRopagation time Segment is programmable to be 1, 2, ..., 8 TQ long.
• PHS1: PHase Segment 1 is programmable to be 1, 2, ..., 8 TQ long.
• PHS2: PHase Segment 2 is programmable to be PHS1 and
• INFORMATION PROCESSING TIME is 2 TQ.
• SJW: (Re) Synchronization Jump Width is programmable between 1 and min(4, PHS1).
PROCESSING TIME.
– enables a hardware loop back, internal TxCAN on internal RxCAN
– provides a recessive level on TXCAN output pin
– does not disable RXCAN input pin
– freezes TEC and REC error counters
