8.4.1.4 Go-To-Sleep Mode

Go-to-sleep mode is the transitional mode of the device from any state to sleep. In this state the driver and receiver are disabled, reducing the current consumption. The INH pin is active in order to supply an enable to the VIO controller which allows the rest of the system to operate normally. If the device is held in this state for t ≥ tGOTOSLEEP the device transitions to sleep mode and the INH turns off transitioning to the high impedance state.

If any wake-up events persist, the TCAN1043A-Q1 remains in standby mode until the device is switched into normal mode to clear the pending wake-up events.
