The Interrupt Status register represents the interrupt status after applying mask bits. Therefore, the status bits are the result of a logical
AND between the raw status and mask bits. The external interrupt pin is derived from this register as an OR function of all non-masked
interrupts in this register.
Reading data from the corresponding register does not clear the status flags automatically. These flags are reset using the corresponding
bits in interrupt clear register.
