2.6 WAKE/ID Function

TCAN24XXEVM WAKE, ID Circuits and Connections Figure 2-9 WAKE, ID Circuits and Connections

Each WAKE/ID input circuit is shown above. Each pin can be configured either as a WAKE pin or as an ID pin on the board. When using a pin as a static WAKE pin, keep the solder joints SJx open and connect the WAKEx/IDx pin to JxA (pull-up to VSUP). The pushbuttons PB1-PB4 can be used to provide a strong pull-down to GND, creating a local wake signal on the respective lines.

To use cyclic sensing wake, connect the respective pin to HSS4_OUT by connecting the WAKEx/IDx pin to JxB.

To use as an ID pin, first enable the ID function via SPI register configuration as outlined in the TCAN24xx-Q1 data sheet. Then, short the respective solder joint SJx to get a series resistance of 510Ω between the IC pin and the external pin. Then, you can connect the pin to GND, connect the pin to VSUP, or leave the pin floating.
