16.6.2 Baud Rate

Baud rate depends on XIN, the division value of the CAN module system clock, the division value of

the prescaler for baud rate, and the number of Tq of one bit.

Table 16.2 shows the examples of baud rate.

Table 16.2 Examples of Baud Rate

Calculation of Baud Rate

Note 1: fCAN division value = 1, 2, 4, 8, 16

fCAN division value: a value selected in the CCLKR register

Note 2: Division value of prescaler for baud rate = P + 1 (P: 0 to 15)

P: a value selected in the BRP bit of the C0CONR register

2 X fCAN division value (Note 1) X division value of prescaler for baud rate (Note 2) X number of Tq of one bit
