Where is the accelerometer

Hi all, I have an iPad 9th Gen (2021) where the rotation is not working. It does rotate but it is always 90 degrees out. So when you hold it in portrait the screen is rotated by 90 degrees as if in Landscape. I cannot find any info on where the accelerometer chip is, any help gratefully received.

I received this iPad as dead. It was a faulty NAND which I replaced with a new NAND after configuring the SYSCFG. It now works fine except for the rotation (please note this is after the restore and before activation (hello Screen), so no other apps loaded.

Thanks once again
