[SOLVED] What does __data20 means in IAR embedded Workbench

shaswat · Mar 16, 2015

Hi all,

Recently I start working on MSP430F6x series micro-controller. I have my reference code and I find out there a keyword

Code:

__data20

Like

Code:

typedef signed long __data20 s32_20;
typedef signed short __data20  s16_20;
typedef signed char __data20  s8_20;

I wants to know what does that means? How and why to use these keywords in the development of code.

Thanks in advance.

It allows you to use the entire memory range (1Mbyte vs 64Kbyte) of the MSP430.

You need to become familiar with the TI 430 Forum
