This register is used to control the state of the CAN transceiver (CAN transceiver state is also dependant upon the SBC
mode). When it is read, this register reports the CAN transceiver state and a CAN overtemperature condition
.
Table 58.
TOT
1 => Transceiver overtemperature
0 => normal temperature
The MODE bit selects between the standard and extended physical layer mode.
Any conditions forcing the transceiver to TermVbat lead to reset of TCR0 TCR1 bits.
After power on reset all bits of the register are set to 0. The information TOT is latched.
To reset TOT a read operation of TCR has to be performed. In case of RSTB = low the register content remains unchanged.
