I would like to configure the can_onchip example for a CAN bitrate of 500kbps instead of the 125kbps default. Can this be accomplished simply by changing the values in the ClkInitTable?

// 500kbps
uint32_t ClkInitTable[2] = {
  0x00000005UL, // CANCLKDIV 5
  0x00002301UL  // CAN_BTR 0x2301
};

//instead of 125kbps
uint32_t ClkInitTable[2] = {
  0x00000000UL, // CANCLKDIV 5
  0x00001C57UL  // CAN_BTR 0x2301
};

Calculating the bit time quanta seems a little :(
