Section 15 Controller Area Network (HCAN)
Time Quanta (TQ) is an integer multiple of the number of system clocks, and is determined by the
baud rate prescaler (BRP) as follows. f
The following formula is used to calculate the 1-bit time and bit rate.
Note: f
Example: With a system clock of 20 MHz, a BRP setting of B'000000, a TSEG1 setting of
Table 15.3 Setting Range for TSEG1 and TSEG2 in BCR
Notes: The time quantum value for TSEG1 and TSEG2 is the TSEG value + 1.

TSEG1
A BCR value is used for BRP, TSEG1, and TSEG2.
* Only a value other than BRP[13:8] = B'000000 can be set.
CLK
TQ = 2 × (BPR setting + 1)/f
1-bit time = TQ × (3 + TSEG1 + TSEG2)
Bit rate = 1/Bit time
B'0100, and a TSEG2 setting of B'011:
Bit rate = 20/{2 × (0 + 1) × (3 + 4 + 3)} = 1 Mbps
= φ (system clock)
= f
