关于ZStack-CC2530-2.3.0-1.4.0 系统时钟初始化

osal中timer初始化：

void osalTimerInit( void )
{
  osal_systemClock = 0;
}

hal中初始化：

typedef struct
{
  bool configured;
  bool intEnable;
  uint8 opMode;
  uint8 channel;
  uint8 channelMode;
  uint8 prescale;
  uint8 prescaleVal;
  uint8 clock;
  halTimerCBack_t callBackFunc;
} halTimerSettings_t;

typedef struct
{
  uint8 volatile XDATA *TxCCTL;
  uint8 volatile XDATA *TxCCH;
  uint8 volatile XDATA *TxCCL;
  uint8 volatile XDATA *TxOVF;
  uint8 ovfbit;
  uint8 intbit;
} halTimerChannel_t;

/*********************************************************************

static halTimerSettings_t halTimerRecord[HW_TIMER_MAX];
static halTimerChannel_t  halTimerChannel[HW_TIMER_MAX];

void HalTimerInit (void)
{
  T1CCTL0 = 0;    /* Make sure interrupts are disabled */

  T4CCTL1 = 0;    /* Make sure interrupts are disabled */

  /* Setup prescale & clock for timer0 */
  halTimerRecord[HW_TIMER_1].prescale    = HAL_TIMER1_16_PRESCALE;
  halTimerRecord[HW_TIMER_1].clock       = HAL_TIMER_32MHZ;
  halTimerRecord[HW_TIMER_1].prescaleVal = HAL_TIMER1_16_PRESCALE_VAL;

  halTimerChannel[HW_TIMER_1].TxOVF =   TCNH_T1OVF;
  halTimerChannel[HW_TIMER_1].ovfbit =  TCHN_T1OVFBIT;
  halTimerChannel[HW_TIMER_1].intbit =  TCHN_T1INTBIT;

  /* Setup Timer3 Channel structure */
  halTimerChannel[HW_TIMER_3].TxCCTL =  TCHN_T3CCTL;
  halTimerChannel[HW_TIMER_3].TxCCL =   TCHN_T3CCL;
  halTimerChannel[HW_TIMER_3].TxCCH =   TCHN_T3CCH;
  halTimerChannel[HW_TIMER_3].TxOVF =   TCNH_T3OVF;
  halTimerChannel[HW_TIMER_3].ovfbit =  TCHN_T3OVFBIT;
  halTimerChannel[HW_TIMER_3].intbit =  TCHN_T3INTBIT;

  /* Setup Timer4 Channel structure */
  halTimerChannel[HW_TIMER_4].TxCCTL =  TCHN_T4CCTL;
  halTimerChannel[HW_TIMER_4].TxCCL =   TCHN_T4CCL;
  halTimerChannel[HW_TIMER_4].TxCCH =   TCHN_T4CCH;
  halTimerChannel[HW_TIMER_4].TxOVF =   TCNH_T4OVF;
  halTimerChannel[HW_TIMER_4].ovfbit =  TCHN_T4OVFBIT;
  halTimerChannel[HW_TIMER_4].intbit =  TCHN_T4INTBIT;
}

void InitBoard( uint8 level )
{
  if ( level == OB_COLD )
  {
    // Interrupts off
    osal_int_disable( INTS_ALL );
    // Turn all LEDs off
    HalLedSet( HAL_LED_ALL, HAL_LED_MODE_OFF );
    // Check for Brown-Out reset
    ChkReset();
  }
  else  // !OB_COLD
  {
    /* Initialize Key stuff */
    OnboardKeyIntEnable = HAL_KEY_INTERRUPT_DISABLE;        //DISABLE
    HalKeyConfig( OnboardKeyIntEnable, OnBoard_KeyCallback);
  }
}

这里也没有

我把hal_timer.h中HalTimerConfig和HalTimerStart屏蔽了也没有报错

请问系统时钟是在哪里开启的
