Bit Timing and Baud
Rate
FSM’s (Finite State Machine) of the CAN channel need to be synchronous to the time
quantum. So, the input clock for bit timing is the clock used into CAN channel FSM’s.
Field and segment abbreviations:
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 superior or eual to the Information
Processing Time and inferior or equal to TPHS1
INFORMATION PROCESSING TIME is 2 TQ.
SJW: (Re) Synchronization Jump Width is programmable to be minimum of PHS1
and 4.
The total number of TQ in a bit time has to be programmed at least from 8 to 25.
Figure 40. Sample and Transmission Point
The baud rate selection is made by Tbit calculation:
Tbit = Tsyns + Tprs + Tphs1 + Tphs2
1.
Tsyns = Tscl = (BRP[5..0]+ 1)/Fcan = 1TQ
2.
Tprs = (1 to 8) * Tscl = (PRS[2..0]+ 1) * Tscl
3.
Tphs1 = (1 to 8) * Tscl = (PHS1[2..0]+ 1) * Tscl
4.
Tphs2 = (1 to 8) * Tscl = (PHS2[2..0]+ 1) * Tscl
Tphs2 = Max of (Tphs1 and 2TQ)
5.
Tsjw = (1 to 4) * Tscl = (SJW[1..0]+ 1) * Tscl
The total number of Tscl (Time Quanta) in a bit time must be comprised between 8 to
25.
