Interrupt Status 0 and Interrupt Status 1 registers represent 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 terminal is derived from this register as an OR function

of all nonmasked 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 the Interrupt Clear 0 and Interrupt Clear 1 registers.
