How can we Differentiate between Dout/RDY pin. ? (Part number : ad7124-4) How can we handle interrupt. on Dout/RDY pin?

Question

Part number : AD7124-4 I'm testing a code using Nucleo-L476RG and an analog-to-digital converter. This ADC uses SPI communication and shares its RDY (end of conversion) and DOUT functions on the same pin, that is, after reading the converted data on the pin, it becomes an RDY pin and can drive an external interrupt on the microcontroller. 
 My question is: how can I enable the External Interrupt event on a pin already configurated as MISO of SPI 
 Since both the functionality relays on 1 common pin, If you have an, example code on Interrupt it will be useful for us to move further

Hi GeorgeADI , 
 Apologies for missing the thread. In a case where the DOUT/RDY is shared with the MISO pin, you may connect the MISO pin to an Arduino pin via a jumper (say D8 for example) and make D8 as the source of interrupt. This was done with AD717x example code; it uses a different ADC but it can be used as a reference along with AD7124 example codes to generate their code specific for AD7124. 
 You may refer to this link AD717x IIO Application [Analog Devices Wiki] or visit the AD7175-8 and AD7124-4 product page for your reference. 
 
 Thanks and regards,
