Avoid Ram Clear in Startup

$

Hi everybody,

Is there any way to avoid clearing the RAM During MCU reset, and Startup ?

I'm using IAR MSP430 Version 5.20 and my chip is cc430f6137

i tried :  #define IGNORE_DATA16_DATA       (i saw it in cstartup.s43) but it seems has no effect because after a reset all ram space is set to zero.

i know i can lock R4 & R5 registers but i need more than 32 bit space of RAM


thank you in advance
