Other Parts Discussed in Thread: MSP430F47186, CODECOMPOSER

I am using

- MSP430F47186

- IAR EW for MSP430

In the memory information after compiling code, I obtain from IAR EW like

CODE : 34 840

DATA: 6 767

CONST: 2 100

In IAR EW document (EW430_CompilerReference.pdf), the explanation of these memory segments is

-----

CODE - for executable code

DATA - for data placed in RAM

CONST - for data placed in ROM

-----

I would like to know the maximum size for CONST (ROM) memory for MSP430F47186.

In msp430F47186.pdf, page 16, I found "memory organization".

In this Table (memory organization), which parts corresponds to "CONST" memory type?

Does the 1st category in the table (i.e. "Memory > Main: code memory | Flash") includes both

- Code

- CONST memory segment

in the one memory segment?

I am using CodeComposer, there you can look at the *.map file after building the project.

In my code all the const is always put into the Flash segment of the device, so the Flash size will determine the const size basically.

CODE and CONST are both stored in Main Flash. ROM is for BSL only and size of ROM is only 512 bytes.

Thank you very much for your reply.

I understand that Flash size is the size for const and other code.

Thank you very much for your reply.

I see that CODE and CONST are both in Main Flash.

Also I could understand the meaning of "size of ROM (512 bytes)" in the table thank to your reply.
