A read-write operation must always be executed with respect to the DRDY signal. Only when the DRDY signal pulses High, a new read or write operation can be initiated. If the DRDY signal is not controlled after a read or write operation, from or to the DRP port, it is not certain that the written bits are set or the obtained bits are representing the value of the register.
