Hello Akhilesh Vernekar

Please have a look at the Table 262. Bus Timing Register (BTR: CAN1BTR - address 0xE004 4014, CAN2BTR -
address 0xE004 8014, CAN3BTR - address 0xE004 C014, CAN4BTR - address
0xE005 0014) bit description  for TSEG2 field as attached.

In summary, the equation is simple as  VPB/(BRP+1)/(TESG1+TSEG2+3).

Have a great day,
TIC
