19.8 Bit-rate
Table 19.2 Examples of Bit-rate
NOTES:
Bit-rate depends on f1, the division value of the CAN module system clock, the division value of the baud
rate prescaler, and the number of Tq of one bit.
Table 19.2 shows the Examples of Bit-rate.
19.8.1 Calculation of Bit-rate
1. The number in ( ) indicates a value of “fCAN division value” multiplied by “baud rate prescaler division value”.
2. 24 MHz is available Normal-ver. only.
NOTES:
2 ✕ “fCAN division value
1. fCAN division value = 1, 2, 4, 8, 16
2. Baud rate prescaler division value = P + 1 (P: 0 to 15)
