I am designing a module where low voltage threshold for interrupts
are desirable. A high of 0.5V and low of 0.2V are ideal but I am not sure
if current interrupt hardware can distinguish this kind of subtle
difference.I would appreciate it if anybody could tell me whether this is
possible, or how difficult it may be, or some reference systems which
has implemented such low voltage-threshold interrupts.

Thanks in advance,
