When does the CAN BUS node automatically start to adjust the baud rate setting in an unknown baud rate network?

[a_ziliu]

The CAN BUS node in the unknown baud rate network will generate bus errors if its baud rate is not consistent with the bus.
As long as the following two conditions are met, the CAN BUS will automatically adjust the baud rate until it receives the correct data.
In the CAN status register, the Epass (CAN STATUS[5]) is set to 1
In the CAN error count register, the RP (CAN_ERR[15]) is set to 1
