NOTES:
1. When the Reset bit is set to "1" (CAN
"1" (Reset mode).
2. Change this bit only in the CAN reset/initialization mode.
3. When using CAN0/1 wake-up interrupt, set these bits to "1".

NOTES:
1. When the TSReset bit = 1, the CiTSR register is set to "0000h". After this, the bit is automatically set to "0".
2. When the RetBusOff bit = 1, the CiRECR and CiTECR registers are set to "00h". After this, this bit is automatically set to "0".
3. Change this bit only in the CAN reset/initialization mode.
4. When the listen-only mode is selected, do not request the transmission.
