Hw to use the offset and gain of adc of MSC1210y5

HI ,
I am working on msc1210y5, in tht i am very much confused with the adc callibration process. I didnt undersatand why i have to dump initial 4 conversions when ever i start accquiring adc.. In a example of msc1210 from keil it says tht we hv 2 dump initial 4 adc conversions . And again i didnt understand abt its offset and gain setting register.

And its mentioning abt "tdata"(adc conversion time) which i didnt understand

Please , if u can explain me abt all these thing thn it will be very helpful for me......

Thanking u

can u please tell us a link to the datasheet of the ADC it is very important to know the conversion principle before talking any thing abt it
