PMBASE1 – Prefetchable Memory Base Address Register –
Device #1
Address Offset:
24-25h
Default Value:
FFF0h
Access:
Read/Write, Read Only
Size:
16 bits
This register controls the host to AGP prefetchable memory accesses routing based on the following
formula:
PREFETCHABLE_MEMORY_BASE1=< address =<PREFETCHABLE_MEMORY_LIMIT1
The upper 12 bits of the register are read/write and correspond to the upper 12 address bits A[31:20] of
the 32-bit address. The bottom 4 bits of this register are read-only and return zeros when read. The
configuration software must initialize this register. For the purpose of address decode address bits
A[19:0] are assumed to be 0. Thus, the bottom of the defined memory address range will be aligned to a
1-MB boundary.
