ADS1298: Two ADS1298 chips are connected in a daisy-chain configuration, and results can only be read once for every two DRDY signals.

I am using two ADS1298 chips connected in a daisy-chain configuration. I read 54 bytes of data via SPI each time a DRDY response is received. The AD data can be read during the first DRDY signal, all data read during the second DRDY signal is 0, AD data can be read again during the third DRDY signal, all data read during the fourth DRDY signal is 0, and so on. After testing, it is found that there is a jump signal on DAISY_IN.

My register configurations are as follows:

CONFIG1: 0x85;

CONFIG2: 0xD4;

CONFIG3: 0xCC;

I hope to receive a response. Thank you very much.
