Dear All,
I am facing an issue in my CAN transceiver circuit that is not able to come out from standby mode even if there is a valid CAN message in the CAN bus;
I have observed that the voltage at STB pin is always HIGH (more than 3.3V).
Please help me clarify below points
- Does it have an Internal pullup resistor in TCAN1044 so that the STB pin will be internally pulled up to HIGH during sleep mode?
- Is it possible to control the STB pin by MCU?
- During wakeup from the standby mode how
- What will happen once there is a wakeup request (CAN message) over bus; Is the STB pin internally pulled down to LOW without intervention of MCU or the MCU needs to Pulldown it?
