Bit Timing
Each node in a CAN network has its own clock, and no clock is sent during data transmission. Synchronization is done by dividing each bit of the frame into a number of segments: synchronization, propagation, phase 1 and phase 2. The length of each phase segment can be adjusted based on network and node conditions. The sample point falls between phase buffer segment 1 and phase buffer segment 2, which helps facilitate continuous synchronization. Continuous synchronization in turn enables the receiver to be able to properly read the messages.

“Scarlett OHara: Oh, oh, Rhett. For the first time Im finding out what it is to be sorry for something Ive done.
Rhett Butler: Dry your eyes. If you had it all to do over again, youd do no differently. Youre like the thief who isnt the least bit sorry he stole, but hes terribly, terribly sorry hes going to jail.”
