3.4.2 WDT Keepalive Register (WKPA)

When enabled, the Watchdog Timer is prevented from resetting the system by
writing to the WDT Keepalive Register (WKPA) located at offset 0x0C from the
address in BAR2 within the selected timeout period. The data written to this
location is irrelevant.
The VMIVME‐7807/VME‐7807RC provide 32 KByte of non‐volatile RAM. This
memory is mapped in 32 Kbytes of address space starting at the address in BAR1.
This memory is available at any time and supports byte, short word and long
word accesses from the PCI bus. The contents of this memory are retained when
the power to the board is removed.
