During power up if EN is low the device enters standby mode. Standby mode is entered whenever a wake up event occurs through LIN bus while the device is in sleep mode. The LIN bus slave termination circuit is turned on when standby mode is entered. Standby mode is signaled through a low level on RXD. See Standby Mode Application Note for more application information.
When EN is set high for longer than tMODE_CHANGE while the device is in standby mode the device returns to normal mode and the normal transmission paths from TXD to LIN bus and LIN bus to RXD are enabled.
