没有中断子程序

如果打开中断，并且打开总中断，但是没有中断子程序，那么该怎样执行？
比如：官方给的2553中ADC10程序：
#include  "stm32F0g2553.h"

long temp;
long IntDegF;
long IntDegC;

void main(void)
{
  WDTCTL = WDTPW + WDTHOLD;                // Stop WDT
  //Configure ADC10
  ADC10CTL1 = INCH_10 + ADC10DIV_3;       // Choose ADC Channel as Temp Sensor
  ADC10CTL0 = SREF_1 + ADC10SHT_3 + REFON + ADC10ON + ADC10IE;       //Choose ADC Ref source
  __enable_interrupt();                   // Enable interrupts.
  TACCR0 = 30;                            // Delay to allow Ref to settle
  TACCTL0 |= CCIE;                         // Compare-mode interrupt.
  TACTL = TASSEL_2 | MC_1;                // TACLK = SMCLK, Up mode.
  LPM0;                                  // Wait for delay.
  TACCTL0 &= ~CCIE;
  __disable_interrupt();                      // Disable timer Interrupt
  while(1)
  {
ADC10CTL0 |= ENC + ADC10SC;          // Sampling and conversion start
__bis_SR_register(LPM0_bits + GIE);       // LPM0 with interrupts enabled

// oF = ((A10/1024)*1500mV)-923mV)*1/1.97mV = A10*761/1024 - 468
temp = ADC10MEM;
IntDegF = ((temp - 630) * 761) / 1024;

// oC = ((A10/1024)*1500mV)-986mV)*1/3.55mV = A10*423/1024 - 278
temp = ADC10MEM;
IntDegC = ((temp - 673) * 423) / 1024;

__no_operation();                      // SET BREAKPOINT HERE
  }
}
里面呢，ADC10和TIMERA出现中断，但是没有中断程序，中断之后是顺序执行吗？
