ADVANCE INFORMATION
The ERROR pin is an open-drain output that drives low when an error is detected. The ERR_FLAG of the data port STATUS header byte is the inversion of the ERROR pin. An error condition is derived from the OR of the SPI STATUS register error field. The error is cleared when the SPI STATUS error bits are cleared, at which time the ERROR output releases. In hardware control mode, there is no access to the STATUS register, therefore an error is only caused by the ADC_ERR bit. Reset or power-cycle the ADC to clear an ADC_ERR.
An external pullup resistor is required for the ERROR pin output. If ERROR pins from multiple devices are connected together, interrogate the devices to determine the device with the error.
