BAR0 is used to access ACE memory space. The ACE is allotted a maximum of
64K words, 128K bytes, for its memory space.
BAR0 will read back as
FFFE0000 after all Fs are written to it. BAR0 will read back the same for both
the 4K word ACE parts (BU-62743/843) and the 64K word ACE (BU-62864).

DEFINITION
00000 – 1FFFC
PCI ENHANCED MINI-ACE Memory Space
PCI ENHANCED MINI-ACE Memory Space: The least significant bit (LSB) of
the PCI address is dropped to form the ACE memory address.
BAR1 is used to access ACE register locations. The ACE is allotted a maximum
of 4K bytes for its register space.
BAR1 will read back as FFFFF000h after all
Fs are written to it. All ACE register locations are accessible through the PCI host
via the BAR1 offsets 000h to 0FCh. The PCI-to-ACE interface control/status
registers are at 800h to 81Ch. PCI accesses outside of these specific regions
(e.g., to offset 100h or 820h, etc.) will produce Target Aborts.

PCI ENHANCED MINI-ACE Register Space: Register accesses are on a 32-bit
boundary: the last 2 bits of the PCI address are dropped to form the ACE
address. (e.g. 000 = ACE Reg 0, 004 = ACE Reg1, 008 = ACE Reg2, etc.).
