| Some of the voltage outputs are programmable via registers, so it appears to be possible to damage your CHIP computer by writing the wrong data to certain registers on this chip. | Some of the voltage outputs are programmable via registers, so it appears to be possible to damage your CHIP computer by writing the wrong data to certain registers on this chip. | ||
