    Hi All,
    
 
    I am interfacing LT4015 battery charger controller board with STM32 through I2C & able to write and read registers of LT4015 but unable to clear SMBALERT interrupt in my source code. 
    
 
    Please, can any one help me out to clear the SMBALERT. 
    
 
    I have tried with below sequence in my code to clear the  meas_sys_valid_alert interrupt.
    
 
    
   1. Reading ARM_SHIP_MODE (0x19) register to perform ARA command.
 
    
 
    
   2. Reading LIMIT_ALERTS (0x36)
 
    
 
    
   3. Disabling en_meas_sys_valid_alert in EN_LIMIT_ALERTS(0x0D) by writing 0.
 
    
 
    
   4. Disabling force_meas_sys_on in CONFIG_BITS by writing 0.
 
    
 
     
 
    
 
    
  Thanks in Advance...
