Fascinating read, although I take issue with its title that implies that it's a bug in the chip. Maybe a bug in the author's code (when he wrote wrong values to the register), definitely not a bug in the chip but a feature. If you write undocumented values into a register, undocumented stuff happens. A lot of ICs have undocumented test modes that are used by the manufacturer.
