5.5 Buffer memory NVRAM
Depending on the configuration ordered, the motherboard is equipped with an NVRAM that
applications can use to back up data in the event of a power failure.
Failure of the supply voltage for a duration longer than 5 ms is indicated by the DC FAIL signal.
Depending on the system utilization, up to 512 KB can be saved in the NVRAM.
A memory window with a maximum size of 512 KB can be displayed by means of PCI address
register. The base address is initialized by the BIOS.
A corresponding function is implemented there for using the NVRAM under WinAC RTX and
for using the CPU150xS SW controller.
