LP8860-Q1: About the case when I can not write at the time of shipment by choosing a different version because there is no good version.

Hi Koji-san,

If the NVM is burned, after a power on reset or VDDIO/EN cycle, the NVM register values will reset to the burned data. If the NVM is just written without burned, the NVM registers will reset to the last burned data.
Do you want to rewrite the NVM every time the device is powered on? Or rewrite and burn the NVM just once before production?

Hi Shirley-san

Thank you for quick response.

I understood that what was written in NVM do not disappear unless it was rewritten.

I think that it only writes in NVM tailored to customer use once.

However, customers are planning to evaluate prototypes and may be rewritten.

When is it recommended to rewrite NVM (60h-78h) after applying power ?
