Baud Rate
Baud rate depends on X
prescaler for baud rate, and the number of Tq of one bit.
Table 1.19.2 shows the examples of baud rate.

Note: The number in ( ) indicates a value of "f
for baud rate".
Calculation of Baud Rate
2 ✕ "f division value (Note 1)" ✕ "division value of prescaler for baud rate (Note 2)" ✕ "number of Tq of one bit"
CAN
Note 1: f division value = 1, 2, 4, 8, 16
CAN
f division value: a value selected in the CCLKR register
CAN
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
