Base2 + 8 :
The value written to this register determines the watchdog time-out
period in multiples of 2 sec. Valid entries are 1 to 127( 2 to 254 seconds).
When this address is read, a refresh of the watchdog timer is generated. The
value read from this address is extraneous.
Base2 + 9 :
Writing to this register enables the watchdog timers and the various
interrupt sources. Reading this register returns the enable register status and the
board IRQ status. The bit assignments are tabulated below:

Base2 + A :
This register allows the PCI-WD to provide a number of different
output actions in response to a fault condition. These outputs are; a system reset,
a relay contact change over, a buzzer sounding, an LED illuminating and an
open collector transistor output being driven. By setting the appropriate bits of
this register any combination of the above outputs can be activated on the
occurrence of a fault condition. This register is write only.
