Table 18.2
NOTE:
Calculation of Baud Rate
1. The number in ( ) indicates a value of fCAN division value multiplied by division value of the baud
Baud rate depends on system clock, the division value of the CAN module system clock, the division value of
the baud rate prescaler, and the number of Tq’s in one bit.
Table 18.2 shows the Examples of Baud Rate.

rate prescaler.
1 Mbps
NOTES:
1. fCAN division value = 1, 2, 4, 8, 16
2. Division value of prescaler for baud rate = P + 1 (P: 0 to 15)
Baud Rate
2 x fCAN division value
fCAN division value: a value selected in the CCLKR register
P: a value selected by the BRP bit in the C0CONR register
