中断程序：
       #pragma vector = PORT1_VECTOR
__interrupt void PORT1_ISR(void)                            // interrupt handler
{
   
    P1IFG &= ~BIT5;
    __bic_SR_register_on_exit(LPM3_bits);
}
中断的设置在main（）中：
  P1IE |= BIT5;                             // P1.5 interrupt enabled
  P1IES &= ~BIT5;                           // P1.5 Low to High edge
  P1IFG &= ~BIT5;                           // P1.5 IFG cleared

编译时出现错误：
Error[Be004]: function "PORT1_ISR" (declared at line 1272 of "D:msp430_prosourceapps eg_read eg_read.c") has overlaid vector with function  
"port1_ISR" (declared at line 343 of "D:msp430_prosourceComponents argetssrf05_ccmsp2618hal_digio.c"), second vector deleted
请问这个问题该怎么解决
