Bits 7 to 0: AIS Interrupt Channel n (AISISn). This bit is set when AIS transitions from a 0 to 1 or 1 to 0. The
interupt for LIUn is enabled in AISIE. This bit when latched is cleared by a read operation to the register if
GISC.CWE is reset. This bit when latched is cleared by a write operation to the bit if GISC.CWE is set.
