(1) Time segment 1: TSEG13 to TSEG10
This is a 4-bit register to set the sampling point.
The relationship between bit content and TSEG1 is as follows:
At reset, TSEG13 to TSEG10 are set to "0000".
(2) Time segment 2: TSEG22 to TSEG20
This is a 3-bit register to set the transmit point.
The relationship between the bit content and TSEG2 is as follows:
At reset, TSEG22 to TSEG20 are set to "000".

5. CAN bus timing register 1 (BTR1: 2Ehex)
This register sets the sampling count, sampling point and transmit point used for bus timing.
Writing to the BTR1 bit is enabled, when the INIT bit of the CAN control register (CANC:
0Ehex) is "1".
The bit configuration is as follows:
