Sensor Driver Recovery via Internal Voltage and Clock Signal Sensing

The sensor driver includes an internal sensing unit that continuously monitors its own operational state (voltage, clock signals) and can autonomously detect abnormal conditions. When an abnormality is detected, the sensing unit immediately generates a recovery signal to trigger firmware reinitialization, eliminating the delay that would occur if the application processor had to wait for or detect the abnormality first. This preliminary self-detection and self-triggered recovery action resolves the contradiction by maintaining touch input sensing capability during the firmware transfer process.

The patent extracts the abnormality detection and notification function from the main data communication channel between the application processor and sensor driver. By creating a separate, dedicated recovery channel specifically for abnormality signals, the system achieves immediate notification of sensor driver issues without interfering with or complicating the existing firmware transfer and data communication channels. This extraction resolves the contradiction by providing fast abnormality notification while maintaining clear separation of functions, thus managing overall system complexity.

The sensor driver is equipped with self-diagnostics capabilities through an internal sensing unit that continuously monitors its own operational parameters (voltage levels, clock signal integrity). When abnormalities are detected, the sensing unit autonomously generates recovery signals to trigger firmware reinitialization from the application processor. This self-service monitoring and self-triggered recovery mechanism resolves the contradiction by enabling rapid firmware retransfer and reinitialization without flash memory, thus maintaining operational reliability while accepting the direct transfer architecture.
