    ADC read giving value more than its resolution .

    alok.nigam_2735181

      I am using CY8CKIT-044 kit for development .I am using VDD as reference and channel is configured as 12 bit resolution .

      For voltage range below 3.3 it is working fine .

      However if i apply 3.3 volt to channel ,reading sometimes exceed 4095 like 4096 and 4097 ,

      since it has 12 bit resolution how values are coming more than that . I want to understand why it is happening and is it normal

      or not .

      Below are the settings that i have used and isr snippet:
