1. A system including a touch sensor controller, the touch sensor controller configured to perform steps comprising:
obtaining touch detection data and outputting the touch detection data to an external processor, the external processor determining touch control data based on the touch detection data;
obtaining pen detection data and outputting the pen detection data to the external processor, the external processor determining pen control data based on the pen detection data;
receiving determination data including the touch control data and the pen control data from the external processor; and
performing an operation based on the determination data received from the external processor,
wherein the touch sensor controller performs pen detection based on the pen control data fed back from the external processor, and
the touch sensor determines whether to perform a global scan or a sector scan on a basis of the pen control data.
