PRODUCTION DATA.
This is the low-power mode of the device. It is selected by setting STB high. The CAN driver and main receiver are turned off and bidirectional CAN communication is not possible. The low-power receiver and bus monitor are enabled to allow for wake-up requests through the bus. A wake-up request is output to RXD (driven low) for any dominant bus transmissions longer than the filter time tBUS. The local protocol controller (MCU) should monitor RXD for transitions and then reactivate the device to normal mode based on the wake-up request. The CAN bus pins are weakly pulled to GND and the SPLIT pin is off (floating).
