Abstract: A microcontroller authority management execution method includes providing a microcontroller, generating an authority management interface, configuring a user mode and an administrator mode corresponding to the memory resources of the microcontroller by using a development software kit through the authority management interface and determining an available peripheral device set and an available function set used for the user mode through the memory resources when the administrator mode is performed. When the available peripheral device set and the available function set are used under the user mode, the available peripheral device set and the available function set are unchangeable.

Abstract: An integrated circuit and a transmission circuit thereof are provided. The transmission circuit includes an input buffer and a voltage holding circuit. The voltage holding circuit has a first end coupled to the input end of the input buffer, and a second end coupled to a reference voltage end. The voltage holding circuit includes a switch and a diode apparatus coupled in series between the first end and the second end of the voltage holding circuit. The switch is configured to receive a mode signal, and is turned on or cut off according to the mode signal.
