Abstract
An embodiment is able to simplify the design and manufacturing process by unifying the step of writing boot loaders to the integrated circuits.
Claims15
A touch sensing integrated circuit system comprising:
- a first nonvolatile memory configured to store a common boot loader which is capable of performing a master function and a slave function;
- a second nonvolatile memory configured to store the common boot loader which is capable of performing the master function and the slave function;
- a first integrated circuit configured to configure the common boot loader as a first boot loader to operate as a master based on a first external signal;
- and
- a second integrated circuit configured to configure the common boot loader as a second boot loader to operate as a slave based on a second external signal,
- wherein the first boot loader is configured to download a first firmware to operate as the master, and the first firmware is stored in the first nonvolatile memory together with the first boot loader operating as the master, and
- wherein the second boot loader is configured to download a second firmware to operate as the slave, and the second firmware is stored in the second nonvolatile memory together with the second boot loader operating as the slave.
