MEM_MODE resets to 0x00 e v e r y t i m e (stm32f072)

I want to move the isr vector table to SRAM

Related to this question

• I moved my isr vector table to SRAM (linker script)
• Now i want to aliase the memory addr of 0x0000 0000 to be found in SRAM.
• In order to do that i believe i need to change the bits from SYSCFG->CFGR1=0x03, and they need to stay that way for the next tme the system reboots to look for the isr vector table in SRAM.

My problem is , SYSCFG->CFGR1==0 every new reboot, even if i changed to 0x03

Where can i find info about how to set SYSCFG->CFGR1 MEM_MODE bits ?

I found this so far:

I completely missed the info in the ref manual.
