HART i910 microcontroller

Hello dear friends, I'm looking for HART i910 microcontroller datasheet. But, I couldn't find. These microcontroller is used in air conditioner PCB. I'm try to programming it, but I need of the datasheet. Thanks a lot.

It's possibly an in-house number, so there's probably no datasheet for it - it 'may' just be another chip just with a different number on it, but you're unlikely to be able to find what that might be. Basically it's not a device you're supposed to be able to alter, so details are kept private.
