Abstract

The invention relates to a pin control device and method and relates to the field of electronic technology. The device comprises a function selector, a pin selector and a pin function multiplexing controller, wherein the function selector is used for determining a to-be-configured target function according to function configuration information; the pin selector is used for determining a to-be-configured target pin according to pin configuration information and determining a target function multiplexing position, which the target function needs to be mapped to, on the target pin; and the pin function multiplexing controller is used for mapping the target function to the target function multiplexing position on the target pin. Through the pin control device and method, a multiplexing function of an external pin of a chip can be freely mapped to a designated position, therefore, the chip can be flexibly used under the condition of not changing any external hardware layout, development cost of a system circuit board can be lowered, development efficiency is improved, and the portability of the chip is enhanced.

Description

technical field [0001] The present disclosure relates to the field of electronic technology, and in particular, to a pin control device and method. Background technique [0002] In today's electronic technology field, MCU (Microcontroller Unit micro control unit) chips are becoming more and more powerful because of their realizable functions, and their application scenarios are becoming more and more extensive. In the application development process of the MCU chip, it is often encountered that the multiplexing function group of a certain pin cannot be modified after being determined. At the same time, if a new MCU chip needs to be used to replace the original chip, the layout of the original system circuit board needs to be re-planned, resulting in low development efficiency, high development cost, and low portability of the MCU. Contents of the invention [0003] The purpose of the present disclosure is to provide a pin control device and method to solve the problems th...
