This document describes how the ST72521 emulator supports software development for the ST72324 target MCU, as well as the differences between the two and their impact on software development.
This document explains how the ST72521 emulator can be used to develop software for the ST72324 microcontroller, as the two devices are essentially compatible. It focuses on functional differences rather than electrical characteristics or Flash programming aspects that cannot be tested on the emulator.
The note is divided into two sections covering specific emulator versions (ST72521 Cut 1.3 and Cut 1.6) versus the ST72324 Cut 1.0. It details differences regarding Schmitt Triggers, SPI overrun flags, and Timer A functions (IC2 and OC2), providing specific software implementation instructions to ensure code runs without modification on both the emulator and the target chip.
The document highlights differences between the ST72521 emulator and the ST72324 target so you can write software that runs without modification on both.
