This register is updated every ODR cycle, regardless of BDU value in CTRL_REG1.
P_DA is set to 1 whenever a new pressure sample is available. P_DA is cleared
when PRESS_OUT_H (2Ah) register is read.
T_DA is set to 1 whenever a new temperature sample is available. T_DA is cleared
when TEMP_OUT_H (2Ch) register is read.
P_OR bit is set to '1' whenever new pressure data is available and P_DA was set in
the previous ODR cycle and not cleared. P_OR is cleared when PRESS_OUT_H
(2Ah) register is read.
T_OR is set to ‘1’ whenever new temperature data is available and T_DA was set in
the previous ODR cycle and not cleared. T_OR is cleared when TEMP_OUT_H (2Ch)
register is read.
