Chapter 2 Register Descriptions
2 – 40
2.4.15 CAN Status Register 2 (CANS2: BEhex)
This is a register to indicate the error contents for when an error occurs.
If an error occurs, the corresponding flag is set to “1”. It is set to “0” when “0” is written to it from the
microcontroller.
Once a flag of this register is set to “1”, it will not be reset to “0” unless “0” is written to it. Therefore, when a
corresponding error flag is set to “1”, and after that if another error occurs when “0” is not written from the
microcontroller, it results in two error flags, the previous one and the current one, being set to “1”.
The bit configuration is shown below.

Operation varies depending on the
value of the COMPAT bit of CANC2
(8Fhex):
COMPAT = 0: Holds “1” till “0” is
written by the
microcontroller.
COMPAT = 1: Becomes “0” if “0” is
written by the
microcontroller or the
bus off state is
released.
Figure 2-40 CAN Status Register 2 (CANS2)
(1) Bit error flag: BITE
This bit becomes “1” when a bit error occurs.
At reset or after release of the bus off state, this bit becomes “0”.
(2) Stuff error flag: STUF
This bit becomes “1” when a stuff error occurs.
At reset or after release of the bus off state, this bit becomes “0”.
