(1) Interrupt events that occur outside of the region A-B set their respective ag bits in the normal way immediately and can thus trigger a hardware interrupt if the mask
bits are set.
(2) Effectively interrupts are enabled at the rst falling edge of SCL after CS has gone HIGH.
(3) Interrupt events that occur between A and B set their respective ags after the mask bits are cleared, if the cause for the interrupt is still present at point B.
(4) All interrupt mask bits are cleared after the interrupt ag and mask bytes are read.
(5) Software writes to the mask register and enables the required mask bits. Any ags currently set will then trigger a hardware interrupt.
(6) INTX is set HIGH (inactive) after the interrupt ag and mask register are read.
