Hi, 

Customer would like to disable the WUP function, could we set INH_DIS=1 and nWKRQ_CONFIG=0 to disable the WUP function for the system? Thanks.

    Wayne,

    This will lower the current consumption is standby mode, but the device will still transition from sleep to standby if a WUP event occurs, This function can't be disabled, however, externally your system won't technically know through any indication from the TCAN4550. Though SPI will be re-enabled in standby mode.

    Regards,
