 Hi,

Please provide your valuable inputs here.!

As per section 8.4(AN11983) EEE driver copies data from FlexNVM to FlexRAM...When it will be happened...? and in which scenario this copying done, whether in after every reset or after every Write operation or after SETRAM command execution...?

Here my doubt is after copying data from FlexNVM to FlexRAM calculating 1st CRC on EEDATA. Later performing SETRAM command to switching from EERAM to SRAM, again switching back from SRAM to EERAM…what is the use of this switching...?

I understood because of switching from SRAM to FlexRAM data copied once again from FlexNVM to FlexRAM...Please correct if any mistake here. In this case also Same data copying to EERAM. what is the use of calculating 2nd CRC on same data...?

Please provide detailed description for the section 8.4.

 

Thanks in Advance.!
