This register is boot-loaded at power-up with a value that indicates the amount of address space required for the
Board ID Registers (16 DWORDs or 64 bytes are required). During power-up the PCI host system reads this register
to determine the size of the address region and assigns a base address. The PCI host writes the assigned base address
in this register. The user application can determine the assigned address by reading Base Address One (BADR1).
This register is read only to the user application. The Board ID Register space is defined as 32-bit (DWORD) access
only.

This register is boot-loaded at power-up with a value that indicates the amount of address space required for the
Acquisition Control registers and LUTs (256K DWORDs or 1MB required). During power-up the PCI host system
reads this register to determine the size of the address region and assigns a base address. The PCI host writes the
assigned base address in this register. The user application can determine the assigned address by reading Base Ad-
dress Register Two (BADR2). This register is read only to the user application. The Acquisition Control Register
Address space is defined as 32-bit (DWORD) access only.
