TCAN4550-Q1: Drive GPO2 directly from SPI

Part Number: TCAN4550-Q1

Dear e2e support,

Could you confirm if there is any way to drive the GPO2 directly from the SPI bus; or can we only configure it through the watchdog or interrupt functions?

Regards,

    Hi Sebastien, 

    Unfortunately, the GPO2 pin can only be used for the configurations available in the GPO2_CONFIG bit field (or used in test modes, which would likely not be helpful here). The GPO state can not be manually driven via a SPI write. 

    Let me know if you have any more questions. 

    Regards,
