How to Use TCM with XC32 Compiler on Cortex®-M7 Based MCU
Introduction
The Microchip SAMS70/E70/V7x series microcontrollers (MCUs) are high-performance MCUs based on the Arm® Cortex®-M7 core. This series of MCUs offers rich peripherals and built-in large-capacity code and data memory. To ensure high-speed, low-latency, and deterministic access to time-critical code and data, the Arm Cortex-M7 core is connected to tightly coupled memory (TCM).
This document describes how to use TCM functionality in SAM MCUs through the MPLAB® X IDE and MPLAB XC32 compiler, as well as the MPLAB Harmony v3 software development framework.
