MSP430F233: Question about Byte or Word Write

Green Deng

Part Number: MSP430F233

Dear team:

One of my customers has questions about the description in the document, Can you explain it for me?

www.ti.com.cn/.../slau144j.pdf

The above paragraph can be found on page 315 of the chip manual msp430x2xx family user's Guide. There are some questions about this paragraph:

He want to know how to understand "initiating from within flash memory" and "executing from RAM"? How to start in flash or ram?

It would be better if we could combine it with an easy to understand code example.

Best Regards

It is covered with (assembler) code examples in 2xx family datasheet. And it is clear.

If program is executing from RAM (program that writing to flash is copied / relocated to RAM) than CPU is not stooped, it continue with executing code. Flashing from program executing in RAM is faster and using flash block write is only possible in this case.

I remember that topics, how to configure function in CCS that should be copied to RAM end executed there, exist somewhere here on e2e.

Hi Green,

Here is an earlier thread with code example:
