I don't think that would make sense. IT8761E has a completely different set
of registers. It is a "Legacy Low Pin Count I/O" only. The other chips are
environmental control chips. I didn't follow the context of this discussion,
but IT8761E does not support a watchdog. It also only supports 16 GPIO pins.
