Hi ,
One of my customer is not able to program required values for reg 0xff (other than 0x0), value remains in 0xA5 even after i2c write with diff values
Kindly check and pls let us know what we are missing. We can also have a short call to go over this issue.
We are referring “DS110DF410 SNLS397D” data sheet.
