Embodiment Construction

[0015] Compare figure 2 and figure 1 It can be found that the serial channel multiplexer with anti-lockout device of the present invention achieves the purpose of anti-lockup of the I2C multiplexer 20 by adding a reset unit 90 component in the system. For example, when the channel between the I2C1C first component 30 and the I2C multiplexer 20 is short-circuited, the channel will be disconnected and cannot be used (locked), and the connection between the I2C multiplexer 20 and the I2C main control unit 10 will be completely broken. interruption. Therefore, before the cause of the short circuit is found out, the system I2C main control unit 10 can be re-transmitted through the I2C multiplexer 20 and other I2C components, such as the I2C second component 40, through the reset unit 90 of the present invention. , I2C third component 50 to be connected.

[0016] Therefore, even under the condition of not excluding the occurrence of lock-up, through the design of the present inv...

Abstract

A multitask processor comprises a serial-channel multitask processor and a reset unit, of which the serial-channel multitask processor is used to connect system having a central processing unit a serial-channel control unit with multiple serial-channel component, the reset unit is connected with the central processing unit and the serial-channel multitask processor. A signal is sent by the serial-channel control unit to the central processing unit for sending a cut-off signal to the reset unit when the connection of serial-channel component, multitask processor and control unit is cut off, and a reset signal is sent by the reset unit to the serial-channel multitask processor to make connection of serial-channel multitask processor, normal serial-channel component and control unit recovered.
