TMS320F280049C: 280049 cpuset Restart

Hi TI experts,

LAUNCHXL-F280049C is my developing board. I'm debugging the program by CCS10.2.
When I click the CCS MENU 'CPU RESET',the program starts at address 0x3fc7a5 .
Then the program runs and stops at file autoinit.h. The source code is like below:

if (&__TI_Handler_Table_Base != &__TI_Handler_Table_Limit)
{
char *const *table_ptr = __TI_CINIT_Base;
char *const *table_limit = __TI_CINIT_Limit;

while (table_ptr != table_limit)
{
char const *load_addr = *table_ptr++;
char *run_addr = *table_ptr++;
char handler_idx = *load_addr++;

handler_fn_t handler = __TI_Handler_Table_Base[handler_idx];
handler(load_addr, run_addr);
}
}

I checked the assembly window and found a strange information.(SEE picture--0x83459.jpg,0x837C4.jpg)
After the program runs at address 0x83459: MOVL XAR7,*+XAR5[0]

@XAR5=0X837C4,*XAR5=0X8340D,

the register @XAR7 should be 0X8340D,.
But the resut of the register @XAR7 is 0x8240D.

So this make my program collapses.

This makes me confused.Why？
