A debugging system includes an embedded device and a terminal computer. The embedded device includes a memory unit, and the memory unit includes a first buffer, the embedded device is configured for executing at least one instruction to generate at least one real-time debugging information, and writing the real-time debugging information into the first buffer. The terminal computer is connected to an in-circuit emulator (ICE) via a first interface, and the ICE is connected to the embedded device via a second interface. The terminal computer uses polling to read the real-time debugging information stored in the first buffer via the ICE, and deletes the real-time debugging information stored in the first buffer afterwards.

An input/output (I/O) buffer circuit includes an I/O unit, a first register and a second register. The I/O unit selectively transmits digital signals and analog signals according to a enable signal, and selectively receives signals and outputs signals at an I/O terminal according to a second enable signal. The first register latches a first control signal received before power is turned off, and outputs the first enable signal corresponding to the first control signal to the I/O unit when power is turned on. The second register latches a second control signal received before power is turned off, and outputs the second enable signal corresponding to the second control signal to the I/O unit when power is turned on.

An embodiment of the invention provides a sensing device. The sensing device includes a controller, a Resistive random memory sensor, an access circuit and a comparator circuit. The access circuit accesses the Resistive random memory sensor. The comparator circuit is coupled to the controller and the access circuit. The controller writes a predetermined data to the Resistive random memory sensor via the access circuit. After a predetermined condition, the access circuit reads a first data from the Resistive random memory sensor. The comparator circuit compares the first data with the predetermined data and transmits a comparison result to the controller. The controller determines whether an abnormal condition occurs based on the comparison result.

A voltage generator and an oscillation device, and an operation method thereof are disclosed. The oscillation device includes a non-volatile memory, the voltage generator and a voltage-controlled oscillation (VCO) circuit. The voltage generator includes a current source. The current source provides a current flowing through the at least one non-volatile memory. The voltage generator uses the non-volatile resistance of the non-volatile memory to generate a bias voltage. The VCO circuit is coupled to the voltage generator so as to generate a corresponding oscillation frequency based on the bias voltage.

An embodiment of an apparatus for securing program code stored in a non-volatile memory is introduced. A non-volatile memory contains a first region and a second region. Two NVMMCS (non-volatile memory management controllers) are respectively coupled to the two regions. A programming command-and-address decoder is coupled to the NVMMCS. The programming command-and-address decoder instructs the first NVMMC to erase data from the first region when receiving a command to erase the first region via a programming interface, and instructs the second NVMMC to erase data from the second region when receiving a command to erase the second region via the programming interface.

A sensing device includes a comparator, a first switch, a second switch, and a controller. The comparator includes a first input end and a second input end. An end of the first switch is connected to one of a first touch electrode and a second touch electrode that are complementary. An end of the second switch is selectively connected to the second touch electrode. When the first touch electrode and the second touch electrode are touched, the controller controls the first switch to connect the first input end and the first touch electrode, controls the second switch to connect the second input end and the second touch electrode, and calculates a first touch position of the first touch electrode and the second touch electrode.

An input/output (I/O) buffer circuit includes an I/O unit and a protection circuit. The I/O unit selectively receives and outputs signals based on an enable signal. The protection circuit generates a logic control signal to deactivate the I/O unit in a state where a voltage level of the I/O terminal is abnormal. The protection circuit includes a register. The register latches a logic signal corresponding to the voltage level of the I/O terminal in a state where the voltage level of the I/O terminal is abnormal, outputs the logic control signal based on the logic signal, and is preset to output the logic control signal based on the logic signal when a power-off state resumes to a power-on state.
