Temperature measurement

[SC97]

Hello,

I am using ses and nrf52840 dk

I wrote the code for reading temperature from the inbuilt temperature sensor and when I read value from TEMP register I am getting 115. I checked the sdk code and I saw the temp value is divided by 4, I am not able to figure out why we divide it by 4. Help please.

Thanks.

Hello,

To make sure the battery is measured, Vref has been divided by 4 or 6. You can read more here

Actually that would be for voltage measurement that too when I choose reference in config register as VDD/4. I am asking about temperature measurement code in the nordic library. The value stored in the TEMP register gets divided by 4 and then we get the final temperature. I was wondering why we have to do that.
