MSP430FR5969-SP: ECC coverage - FRAM, Register, RAM(SRAM)

Tool/software:

Hi Team,

I have some questions for MSP430FR5969-SP.

1. Where is the main firmware stored in? FRAM? 

2. Is register consisted by FRAM or RAM(SRAM)?

3.  Is FRAM cash consisted by FRAM or RAM(SRAM)?

4.  Usually, we pull firmware from Flash to RAM(SRAM) and operate. Does this device pull firmware from FRAM to RAM(SRAM) or operate everything on FRAM?

5.  Does ECC function only applied to FRAM? Is the function also applied to RAM(SRAM)? 

Thanks & Best regards,
