the system clock and the CAN bit segments. Refer to
information on the bit timing registers.
A bit is divided into four separate non-overlapping time segments called SYNC_SEG, PROPSEG, PSEG1,
and PSEG2. These are illustrated in
the segment durations:
The sample point indicated in
bit is selected (CANCTRL1[SAMP] bit = 0). If three samples per bit are selected, the sample point
