It will be grateful if you can help me with a clear understanding of LIN stand by mode operation. As per my understanding, Bus Idle situation happens(no LIN traffic for 4-10seconds), or go-to sleep command received from master, the LIN PHY will go for stand-by mode.
Please help me with the state of LIN PHY, for the below mentioned scenario,
a) The ECU is powered up and there is no LIN traffic for 4-10seconds after powering up the ECU, what will be state of LIN PHY? : Normal mode or Standby mode
b) The ECU is powered up, and at least one LIN frame is transmitted through the bus, and there is no traffic for 4-10seconds, what will be state of LIN PHY? : Normal mode or Standby mode
Hope you got the difference between scenario a and b.
In both the above LINPHY will go to stand by mode.
You can refer the section '2.6.3 GO TO SLEEP' of LIN spec below:
Please feel free to update for any query.
