See also the interrupt status 1 register at subaddress F3h (see Section 2.11.92).
The interrupt status 0 and 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 interrupt clear 0 and 1 registers.
