1. An operation method of a timing controller, comprising:
receiving an instruction signal via a general purpose input/output pin of a touch driver;
starting a detection period according to a main falling edge switched from a first voltage level to a second voltage level of the instruction signal;
detecting a number of sub-falling edges of pulse signals of the instruction signal; and
determining a current operating status of the touch driver according to the number of sub-falling edges of the instruction signal during the detection period,
wherein the timing controller determines that the current operating status of the touch driver is a first writing status according to the number of sub-falling edges of the instruction signal during the detection period being 0.
