The Datasheet of NCT6779D-R

Does Anyone have Nuvoto NCT6779D-R? Not the NCT6779D(non -R)

I have similar board that struggle to power on and can't be forced off with button, try to check the old SIO I think it labeled nct6779D-R(which I cannot find the datasheet anywhere), it may not compatible with nct6779D(non -R), in the motherboard and in boardview near the SIO there's 32.7Khz Oscillator connected to the SIO Pin 91 & 90(I think? I forgot)but in the datasheet of NCT6779D doesn't mention Realtime clock 32.7Khz anywhere
