Title:
A SYSTEM AND METHOD FOR PROGRAMMING DATA TRANSFER WITHIN A MICROCONTROLLER
Document Type and Number:
WIPO Patent Application WO/2017/151588
Kind Code:
A3
Abstract:
A method and system for programming a microcontroller (MCU) to implement a data transfer, the MCU having a flash memory, a central processing unit (CPU) and a direct memory access controller (DMAC). In one embodiment, the method includes calling a function stored in the flash memory, wherein a first parameter is passed to the function when it is called, wherein the first parameter identifies a first data structure that is stored in flash memory, and wherein the first data structure includes first DMAC control values. The CPU reads the first DMAC control values in response to the CPU executing instructions of the function. The CPU then writes the first DMAC control values to respective control registers of the DMAC in response to the CPU executing instructions of the function.
