[求助] 请各位前辈指导

#include "msp430x41x2.h"

void main(void)
{
  WDTCTL = WDTPW + WDTHOLD;                 // Stop WDT
  ADC10CTL0 = SREF_1 + ADC10SHT_2 + REFON + ADC10ON + ADC10IE;
  TACCR0 = 30;                              // Delay to allow Ref to settle
  TACCTL0 |= CCIE;                          // Compare-mode interrupt.
  TACTL = TASSEL_2 + MC_1;                  // TACLK = SMCLK, Up mode.
  __bis_SR_register(CPUOFF + GIE);          // LPM0, TA0_ISR will force exit
  TACCTL0 &= ~CCIE;                         // Disable timer Interrupt
  ADC10AE0 |= 0x01;                         // P7.4 ADC option select
  P5DIR |= 0x02;                            // Set P5.1 to output direction

  for (;;)     
  {
    ADC10CTL0 |= ENC + ADC10SC;             // Sampling and conversion start
    __bis_SR_register(CPUOFF + GIE);        // LPM0, ADC10_ISR will force exit
    if (ADC10MEM < 0x88)                    // ADC10MEM = A0 > 0.2V?
      P5OUT &= ~0x02;                       // Clear P5.1 LED off
    else
      P5OUT |= 0x02;                        // Set P5.1 LED on
  }
}

我想请问 ADC10MEM<0x88   是什么意思？ 和后面注释里  ADC10MEM = A0 > 0.2V 是怎么对应的？

我是初学者，问题可能比较基础，忘前辈们指导。

这个你得结合#include的.h头文件来看才行
