Figure 45. CAN Bit Construction
Synchronization Segment
The first segment is used to synchronize the various bus nodes.
On transmission, at the start of this segment, the current bit level is output. If there is a
bit state change between the previous bit and the current bit, then the bus state change
is expected to occur within this segment by the receiving nodes.
Propagation Time Segment
This segment is used to compensate for signal delays across the network.
This is necessary to compensate for signal propagation delays on the bus line and
through the transceivers of the bus nodes.
Phase Segment 1
Phase Segment 1 is used to compensate for edge phase errors.
This segment may be lengthened during resynchronization.
Sample Point
The sample point is the point of time at which the bus level is read and interpreted as the
value of the respective bit. Its location is at the end of Phase Segment 1 (between the
two Phase Segments).
Phase Segment 2
This segment is also used to compensate for edge phase errors.
This segment may be shortened during resynchronization, but the length has to be at
least as long as the information processing time and may not be more than the length of
Phase Segment 1.
Information Processing Time
It is the time required for the logic to determine the bit level of a sampled bit.
The Information processing Time begins at the sample point, is measured in TQ and is
fixed at 2 TQ for the Atmel CAN. Since Phase Segment 2 also begins at the sample
point and is the last segment in the bit time, Phase Segment 2 minimum shall not be
less than the Information processing Time.
Bit Lengthening
As a result of resynchronization, Phase Segment 1 may be lengthened or Phase Seg-
ment 2 may be shortened to compensate for oscillator tolerances. If, for example, the
transmitter oscillator is slower than the receiver oscillator, the next falling edge used for
resynchronization may be delayed. So Phase Segment 1 is lengthened in order to
adjust the sample point and the end of the bit time.
