Hi TI engineer:

The data read from the register 0x3d (Month, Year/Day) in the IFIB Offset of the BQ8050 chip is 0x6209. How should the year, month, and day be parsed?

Looking forward to your reply! thank you!

Hi Jonny.,

Actually, we want to know how the value in the 0x3d register of the IFIB offset(As shown as below) is used to calculate the year, month, and day.

For example, if the value we read from a certain BQ8050 chip is 0xb409, what would its production date be?

Looking forward to your reply! thank you!
