I have a doubt in strucure padding relavant to code warrior IDE.  I'm working on a 16 bit microcontroller mc9s12xhy.


typedef struct{

unsigned int x;

unsigned char y;




Error_mode Error_mode_Data;


While compiler compiles the code, it shall allocate 4 bytes for Error_mode_Data ( with padding  refernce: .map file ). It doesnt seem to happen. It s allocating 3 bytes only. Hw to switch on/off padding in a code warrior compiler? this is critical coz of im using for EEPROM write/read!
