Hi team,

If SPI wire disconnected and SPIERR flag is high in this device, nINT inserted the low?

    Shoo,

    Yes, a SPI Error will always set the SPIERR flag and the nINT pin will reflect this by going low.

    The nINT pin is the global interrupt pin that will be asserted low when any bit in registers 0x0820 and 0x0824 is set to '1' that has not been disabled in register 0x0830.  Most interrupt bits can be disabled from causing the nINT pin to be asserted, but some bits such as SPIERR cannot be disabled in register 0x0830.

    Regards,

    Jonathan
