7.4.3 Standby Mode

When the device receives a LIN bus wakeup in sleep mode, the device transitions to standby mode. In standby mode, all LIN channels driver are OFF, receiver is ON but RXDx is latched low. If LIN bus wakeup was the reason to transition to standby mode, only corresponding RXD of LIN channel is latched low which received LIN wakeup. INHN can be asserted low to enable Vio to come up if INHN is used to control system power management. Transition of SLP from high to low by MCU and SLP being held low for at least tMODE_CHANGE, transitions the device to normal mode. For the initialization of device in normal mode, tNOMINT time is required.

If device had transitioned to standby mode due to a wakeup event, another wakeup event in standby mode keeps the device in standby mode until MCU forces the device to go to normal mode using SLP pin.

If the device had transitioned to standby mode from Vio UV mode with SLP = high, RXDx is high since wakeup had not forced the device into standby mode.
