The condition for setting this bit to “1” is the same as that of the Interrupt Status Register 1.
Make sure that the condition for clearing this bit to “0” differs as follows.
The condition for clearing this bit to “0” is always the same as in the case of the RDYM bit set to “0”. Hence,
the presence/absence of data in the buffer can be confirmed by reading these bits even after the interrupt is
cleared by writing “0” to the Interrupt Status Register 1.
