Writing To NVRAM Directly?

My setup is a Custom Net+50 board with 128KBytes of Battery Backed SRAM connected to CS3. My question is, Is it possible to write to that memory directly, bypassing a call to NAVNWrite?. I can read from it directly, but when i try to do a write by doing a simple assignement (ie MyPointer->MyVariable = 0x34 where MyPointer points to an address within the 128KBytes of SRAM [NVRAM_BASE + offset]) it crashes the system and causes a reboot. Is there a way to change the BSP so that this type of assignment is possible?

Never Mind, I figured it out. CS3 was write protected. I just had to make sure that the write protect bit never got set. Thanks
