I am using the Lpc11e14 and I need to create a few variable the will not get initialized when I come out of reset. I am putting the Lpc11e14 to sleep and using the WDT to bring the Lpx11exx out of sleep. I would like to keep the variables intact when I come out of sleep. I did a search on un-initialized variable in lpcxpresso and found the following but I could not get it to compile.

volatile int32 __attribute__ ((section(“.noinit”))) variable;

Thanks, Kevin

What is an "int32"? Where is the type int32 defined?

This compiles for me (using a standard C data type):

__attribute__ ((section(".noinit"))) volatile int  variable;
