TM4C MAC ADDRESS programming procedure.

Hello, I need some clarifications about the mac addr writing procedure (I'm not using a flash programmer tool I'm using a JTAG test tool and I'm writing my code)

To set , for example the MAC ADDRESS 11 22 33 44 55 66, I have to

STEP 1 write register 69 USER_REG0:= 0x00332211. Is it correct?

STEP2 commit the USER_REG0 

STEP 2 write register 70 USER_REG1:=0x00665544. Is it correct?

STEP4 commit the USER_REG1 

To commit USER_REGx I have to use the FMC register, haven't I?

I should write FMC [31..16] WRKEY:= 0xA442, COMT [3]:=1 other bits:=0, is it correct?

Thank you

Mauro
