Any modification on one of the fields of the CANBR register must be done while CAN module is disabled.
To compute the different Bit Timings, please refer to the
• PHASE2: Phase 2 segment
This phase is used to compensate the edge phase error.
Warning: PHASE2 value must be different from 0.
• PHASE1: Phase 1 segment
This phase is used to compensate for edge phase error.
• PROPAG: Programming time segment
This part of the bit time is used to compensate for the physical delay times within the network.
• SJW: Re-synchronization jump width
To compensate for phase shifts between clock oscillators of different controllers on bus. The controller must re-synchronize
on any relevant signal edge of the current transmission. The synchronization jump width defines the maximum of clock
cycles a bit period may be shortened or lengthened by re-synchronization.
• BRP: Baudrate Prescaler.
This field allows user to program the period of the CAN system clock to determine the individual bit timing.
The BRP field must be within the range [1, 0x7F], i.e., BRP = 0 is not authorized.
