标题: KL25代码求解
下面是kl25的代码，可是不知道整两个函数相当于K60的哪个模块

void cmp_init ( unsigned char rising_falling )
{
            // Filter and digital hysteresis disabled
         CMP0_CR0 = 0x00;
         // no sample(continuous), no window, -, HS mode,
         // no invert, COUTA(unfiltered), output pin enable, moduledisable
         CMP0_CR1 = CMP_CR1_PMODE_MASK | CMP_CR1_COS_MASK | CMP_CR1_OPE_MASK; //0x16;
         // Filter disabled
         CMP0_FPR = 0x00;
         // Enable rising or falling edge interrupts, clear flags
         CMP0_SCR = //CMP_SCR_IER_MASK |
                              rising_falling |
                              //CMP_SCR_IEF_MASK |
                              CMP_SCR_CFR_MASK |
                              CMP_SCR_CFF_MASK; //0x1E
         // 6-bit DAC enabled, output set to 1/2-scale, Vdd reference
         CMP0_DACCR = CMP_DACCR_DACEN_MASK |
                                 CMP_DACCR_VRSEL_MASK |
                                 CMP_DACCR_VOSEL(0x20); //0xE0;
         // P-input as external channel 0, M-input as 6b DAC
         CMP0_MUXCR = CMP_MUXCR_PSEL(0) |
                                 CMP_MUXCR_MSEL(7); //0x07;

         // enable CMP
         CMP0_CR1 |= CMP_CR1_EN_MASK;
}

void cmp0_isr(void)
{
  GPIOB_PSOR = 0x00080000;          // set Port B 19 indicate wakeup

  printf("\n[CMP0_ISR]****ISR entered*****\r\n\n");
  printf("[CMP0_ISR]CMP0_SCR = %#02X ", (CMP0_SCR ))  ;
  if (CMP0_SCR & CMP_SCR_CFR_MASK) {
   CMP0_SCR |= CMP_SCR_CFR_MASK;
   printf(" CMP0_CFR set and is now clear \n");
   printf("[CMP0_ISR]CMP0_SCR = %#02X ", (CMP0_SCR ))  ;
  }
  if (CMP0_SCR & CMP_SCR_CFF_MASK) {
   CMP0_SCR |= CMP_SCR_CFF_MASK;
   printf(" CMP0_CFF set and is now clear \n");
   printf("[CMP0_ISR]CMP0_SCR = %#02X ", (CMP0_SCR ))  ;
  }
  return;
}
