Part Number: TCAN1145-Q1
Hi, TI Expert
I copy below description from the E2E supprt , and I agree with it .
"
When selective wake is active, the device will use two different states for sleep mode: when the CAN bus is idle, the WUP receiver will be active and monitor the bus for activity. When a WUP is received, the selective wake receiver will become active to monitor the bus for a WUF. In this state, the device is still in sleep mode and INH remains low. If a WUF is received then the device will transition to standby mode and drive the INH pin high. If no WUF is received, the device will remain in sleep mode until the bus returns to an idle state. Once the bus has been idle for > 1sec, the selective wake receiver will be disabled again to save power and the WUP receiver will be enabled to monitor for bus activity
what I want to know is about the RXD level status .
1. When selective wake is active, When a WUP is received, the device is still in sleep mode and INH remains low. how about the RXD level ?(Vsup is always 12V on and Vio is always 3.3V on)
2. When selective wake enabled, WUP received and WUF received,how about the RXD level ?(Vsup is always 12V on and Vio is always 3.3V on)
