REGISTERS
Up to 2 cards are allowed in a system, PCI_1 refers to addresses on one of the extenders and PCI_2 refers to the second one.
The definition of the first and second card are defined by the position of JP15.
DESCRIPTIONS
The PCI_1 responds to address range starting from 0x6X and the PCI_2 card responds to starting from 0xEX address range.
The Jumper JP15 installed on the PCI board makes the board to respond as PCI_1 and jumper removed makes the board to be
PCI_2.

After turning the extender on and before start using the UUT or starting any test program a wait time of about
200 ms must be observed for the reset signal to be de-asserted.
This delay time may have to be adjusted to as long as 5.7 seconds if the reset signal duration has been
reprogrammed by the user.
