SPI DOUT/DRDY multiple pin usagehttps://devzone.nordicsemi.com/f/nordic-q-a/58576/spi-dout-drdy-multiple-pin-usageHi, Working with ads1220 which runs on SPI. There standard SPI pins - dout, din, sclk, drdy. In its datasheet there is written it is possible to merge dout with drdy to indicate new data are available.
