PRODUCTION DATA
EN controls the operational modes of the device. When EN is high, the device is in normal operating mode allowing a transmission path from TXD to LIN and from LIN to RXD. When EN is low, the device is put into sleep or standby mode and there are no transmission paths available. EN has an internal pull-down resistor to ensure the device remains in low power mode even if EN is left floating. EN should be held low until VSUP reaches the expected system voltage level.
