JUMPER # DESCRIPTION
W28-W32 STD Bus Dual Port RAM Addressing
(20-bit) - defines the address range of the
dual port memory as seen by the STD bus
CPU. These jumpers map the ZT 8832 dual
port RAM into any contiguous 32 Kbyte
block within the 1 Mbyte address range for
an STD bus supporting 20 address lines.
The table on page A-9 shows the address
range of the dual port memory for each
jumper combination. Note that the dual
port memory, as seen by the local CPU, is
mapped at address 80000h through
87FFFh.
See jumpers W33-W36 (page A-10) for
mapping the ZT 8832 into the 16 Mbyte
address space for STD bus CPUs that
support 24 address
lines.
