msCAN08 Controller (msCAN08)
• SYNC_SEG: This segment has a fixed length of one time
quantum. Signal edges are expected to happen within this section.
• Time segment 1: This segment includes the PROP_SEG and the
PHASE_SEG1 of the CAN standard. It can be programmed by
setting the parameter TSEG1 to consist of 4 to 16 time quanta.
• Time segment 2: This segment represents the PHASE_SEG2 of
the CAN standard. It can be programmed by setting the TSEG2
parameter to be 2 to 8 time quanta long.
The Synchronization Jump Width can be programmed in a range of 1 to
4 time quanta by setting the SJW parameter.
Above parameters can be set by programming the Bus Timing Registers
CBTR0-1 (see msCAN08 bus timing register 0 (CBTR0) on page 380
and msCAN08 bus timing register 1 (CBTR1) on page 381).
It is the user’s responsibility to make sure that his bit time settings are in
compliance with the CAN standard. Figure 8 and Table 3 give an
overview on the CAN conforming segment settings and the related
parameter values.
