- Application NoteAI-generated Summary: Ensure safety in circuit designs by considering potential semiconductor failures that may cause injury, fire, or damage. Use auxiliary circuits, non-flammable materials, and malfunction prevention. Product information may change without notice, and Renesas disclaims liability for damages from inaccuracies. Semiconductors are not for life-critical systems without prior approval. The document explains C language programming basics, project setup, compiler, assembler, linker, debugger, coding tips, stack estimation, and interrupt handling for the Renesas 740 family microcomputers.
- Application NoteAI-generated Summary: This document explains how to design PCB layouts to enhance noise immunity for the 740 family MCU, using the M37544G2ASP sample at 4 MHz on a single-sided board. It compares recommended and non-recommended layouts, highlighting five key design points: short oscillator wiring, close reset circuit placement, short CNVSS wiring with a resistor, decoupling capacitor placement near MCU, and unified VSS wiring. These principles reduce noise-induced failures and improve MCU stability.
- Application NoteAI-generated Summary: The programming guidelines for the 740 Family in C language have been updated and replaced by a new document titled "C Compiler Package for 740 Family M3T-ICC740 Application Notes" (Document No. REJ06J0005-0100). Users should refer to this new document for current information. Inquiries related to the previous guidelines should be sent via email to the provided contact.
- Application NoteAI-generated Summary: This document explains two methods for handling interrupts in the ICC-740 C Compiler for the 740 Family MCU. Method 1 involves modifying the interrupt vector table in the startup file and declaring interrupt functions with the 'interrupt' keyword. Method 2 deletes the interrupt vector table, reserves data space, and declares interrupt functions using the 'interrupt [offset]' syntax. Examples illustrate how to implement INTO interrupt handling in both methods.
- Application NoteAI-generated Summary: This document explains how to write C-Assembly mixed programs for the 1CC740, focusing on interfacing functions between C and assembly. It details rules for passing parameters and return values based on data types, using specific memory areas like accumulators, C_ARGN, and C_ARGZ. It introduces the assembler interface keyword DEFFN for declaring assembly functions callable from C, and provides examples of setting DEFFN and calling assembly subroutines from C. It also covers saving and restoring registers and flags during calls.
