9.4.5 Standby Mode

This mode is entered whenever a wake-up event occurs through LIN bus or NWake while the SN65HVDA195 is in sleep mode. The LIN bus responder termination circuit and INH are turned on when standby mode is entered. The application system powers up once INH is turned on, assuming the system is using a voltage regulator connected through INH. Standby mode is signaled through a low level on RXD.

When EN is set high while the SN65HVDA195 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.
