SJA1105 can be used between two mcu？

Hello，

My Pcb has two MCU：S32V234 and TC297. If I use a SJA1105 to connect this two mcu, is it OK？

Yes, it is ok.

Thank you Bulat Karymov!

So I chose TC297 to control SJA1105 by SPI,then in my code:

1. Should TC297 initialize SJA1105 first?

2. S32v need initialize SJA1105?

Thanks!

The SJA1105 is configured via SPI, so it should be configured by the controller with SPI connection to the switch.
