Other Parts Discussed in Thread: TCAN1043
RXD pin of TCAN1042VDRQ1 generate a negative pulse when it is shift from standby mode to normal mode,the pulse duration time is about 25ns.
Here is the waveform I have catched.
I have a few questions ：
1， Will RXD suffers a pulse too when TCAN1042DRQ1 shift from normal to standby mode？
2， Is this an Unique feature that only happened in TCAN1042DRQ1？ Or orther Chip models have the same problem too？ such as TCAN1043，TCAN1044...
3，How can I solve this problem besides software solution？I mean is there any hardware solution？
