.
4.9 Dual-Port RAM Jumpers
The
DUAL PORT HI
and
LO
jumpers select the starting address and the
ending address a bus master references to read or write to Dual Port RAM.
The
DUAL PORT LO
jumper block sets the starting VMEbus address and
DUAL PORT HI
selects the ending address. Two additional jumpers (labeled
A32
and
A24
) select whether the card responds to 32-bit or 24-bit address
space.
If the A32 jumper is IN, the window is decoded in VMEbus A32 address
space. If the A24 jumper is IN, the window is decoded in A24 address space
(bits 24 - 31 are ignored). If both jumpers are IN, the window is present in
both A32 and A24 address space.
