According to the current device datasheet (TI Lit # SLAS831D, revised
March 2018) the value written to the device's PAGE register to trigger
a complete register reset should be 0xfe, not 0xff. So go ahead and
update to the correct value.

Does 0xff not reset the device? If so then this is not just a typo but a
bug and this patch should have a fixes tag. Either way:
