MSP430F5659: bitwise shifting left over 15 results in 0

Hi,

I am trying to use uint32_t variables as error flags.

bit shifting over 2 bytes results in a value of 0x0000 however, even when stored in a uint32_t

How can I set bits in the 3rd and 4th bytes of a uint32_t?? Thanks!

#include "stdint.h"

void main() {

uint32_t test = 0;

test |= (1<< 16);

if(test) {

return 0;

}

else {

return -1

}

}
