This register reports the source of a reset already occurred.
RSR0: 1 = > V
RSR1: 1 = > Software watchdog reset occurred (RSR 2 = 1 in this case), 0 = > no SW watchdog reset occurred
RSR2: 1 = > External reset occurred (RSR0 = RSR1= 0 in this case), 0 = > no external reset occurred
Events related to the bits in register RSR are latched. All bits can be reset by a Read operation of the register. After a power-ON reset, RSR2
and RSR0 are set to 1. Therefore, the first read out of the register after power-ON delivers RSR[2:0] = [101].
In case of CANH line failures, the appropriate bit(s) are set according to
Read operation. After power-ON is reset, all bits are set to 0.
In case of CANL line failures, the appropriate bit(s) are set according to
Read operation. After power-ON is reset, all bits are set to 0.
