23.1.3.1
BRP Bit
The BRP bit is used to set the frequency of the CAN communication clock (fCANCLK).
The cycle of fCANCLK is set to be 1 Time Quantum (Tq).
23.1.3.2
TSEG1 Bit
The TSEG1 bit is used to specify the total length of the propagation time segment (PROP_SEG) and
phase buffer segment 1 (PHASE_SEG1) with the value of Tq.
A value from 4 to 16 time quanta can be set.
23.1.3.3
TSEG2 Bit
The TSEG2 bit is used to specify the length of phase buffer segment TSEG2 (PHASE_SEG2) with the
value of Tq.
A value from 2 to 8 time quanta can be set.
Set the value smaller than that of the TSEG1 bit.
23.1.3.4
SJW Bit
The SJW bit is used to specify the resynchronization jump width with the value of Tq.
A value from 1 to 4 time quanta can be set.
Set the value smaller than or equal to that of the TSEG2 bit.
