Title:
MICROCONTROLLER CHIP CONTAINING MULTI-PROTOCOL COMMUNICATION INTERFACE PERIPHERAL AND OPERATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/082472
Kind Code:
A1
Abstract:
Disclosed are a microcontroller chip containing a multi-protocol communication interface peripheral and an operation method therefor, the chip comprising a multi-protocol communication interface peripheral. The multi-protocol communication interface peripheral is connected to a system bus and is connected to an I/O port. The multi-protocol communication interface peripheral comprises a special RISC instruction set microkernel, a code memory and a code program which is stored in the code memory and which may be executed by the RISC instruction set microkernel. The code program at least comprises two bit operation instructions, namely setting 1 and clearing to 0, and the instructions are single-cycle instructions. When the RISC instruction set microkernel executes the code program, the I/O port may output 1 or 0. In the present invention, the interface peripheral of the microcontroller chip is more flexible, thus improving the universality of the microcontroller chip, and the communication protocol thereof may be revised or upgraded, thus reducing part of redundant or standby communication interfaces, and saving costs.
