Part Number: MSP430G2755

Tool/software: TI C/C++ Compiler

A customer has complained that his bellow % operator code was not assembled correctly.

mov.w #(0x232800 % 0x10000),R4 ;NG

He says v15.12 is OK, but v16.9 is NG. He wants to fix this trouble to make his codes compatible.

I have reproduced this trouble as bellow. With using CCSv7, ‘%’ operator cause unjust code while ‘/’ operator make correct code.

CCSv7.3, compiler v16.9.6;

CCSv6.2, compiler v15.12.3;

Unfortunately, I am unable to reproduce the error. Please create a zip file of the CCS project as described in the article Project Sharing, and attach that to your next post.

Thanks and regards,
