Table 49.
In case of CANL line failures, the appropriate bit(s) are set according to table 48. This information is latched and the register
can be reseted by a read operation. After power on reset, all bits are set to 0.
Table 50. RSR — Reset Source Register
This register reports the source of a reset that has occurred
.
RSR0: 1 => VDD1 undervoltage occurred (RSR2=1 in this case), 0=> no undervoltage on VDD1 occurred
RSR1: 1 =>SW watchdog reset occurred (RSR2=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 reseted 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].
Table 51. VSSR — Voltage Supply Status Register
Register used to monitor the status of the V2, V3 and Vbat voltage level.
Table 52.
V2SR: 1=V2 on, 0=V2 off
V3SR: 1=V3 overtemperature, 0=V3 no overtemperature
VBSR1 is a real time information and cannot be reseted. Bits V3SR, V2SR and VBSR0 are latched and can be reseted by a read
operation of the register.
