Why is the screen printing of MFR4310E1MAE40 model 1M63J instead of 0M63J

Why is the screen printing of MFR4310E1MAE40 model 1M63J instead of 0M63J?

There are detailed instructions in the specification, how to read?

Hi @Amiliy 

this marking says which silicon mask set version is used. 1M63J is newer one. It fixes errata MUCts03799 and MUCts03800 from the previous mask set 0M63J.

The errata sheets can be found here:
