Hi TI expert,

According to the application note: "Software Strategies to Achieve Power Optimizations in TI Millimeter Wave Sensors", if I bring down the AWR6843 into "Full Power Down" mode (217.8mW), can I still use external device to wake it up by CAN interface (CAN signal to toggle it awaken)? or need to HW reset the AWR6843 to wake up?

Hi Jesse,

Technically, it is possible to use CAN interrupt to wakeup the device. You just have to ensure to call the APIs to bring the device back up in the correct order after the CAN interrupt or within the CAN interrupt ISR.
