Interrupt Status 0 and Interrupt Status 1 (see Table 2-109) 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.
