Sets the behavior mode of the interrupt registers of the device. In the default configuration, if the interrupt
notification registers are read and any error is found to have occurred since the last clearing of that reg-
ister, the device will automatically set the corresponding mask bit in the appropriate mask register. In the
non-default configuration, the mask bits will not be set automatically.
