ADS1298: The order of command START and SDATAC

Part Number: ADS1298

Hi team,

The customer operates the device according to figure 93 (initial flow at power up) in the datasheet:

After power on reset, the command SDATAC is sent first, and then the registers are configured, and then the command  START is sent. After a delay of 50 ms, the command RDATAC is sent. But there is a problem that DOUT output is always 0.

Later, the customer tried to send RDATAC first, after a delay of 50 ms, and then send START , which solved the problem. However, this flow is inconsistent with figure 93. I would like to know if there are any hidden dangers in this way, and whether it is feasible?
