S5U13705B00C REV. 1.0 ISA BUS EVALUATION
BOARD USER’S MANUAL (X27A-G-005-01)
The S1D13705 contains 80K bytes of embedded, 16-bit, SRAM used for the display buffer and a 32
byte internal register set.
Since the S1D13705 does not distinguish between memory and register accesses, both the 80K byte
display buffer and the 32 byte register set must be memory mapped into the host’s memory space.
When using the S5U13705B00C board on an ISA bus system, the board can be configured to map
the S1D13705 to one of two memory blocks.
The SRAM start address is determined by a DIP switch setting. See “Table 2-1 Configuration DIP
Switch Settings,” on page 4-2.
1. When switch S1-5 is in the closed position, the S1D13705 is mapped into segments 0C0000h
Note: Since VGA and VGA compatible video adapters use address 0C8000, these cards cannot be
2. When switch S1-5 is in the open position, the S1D13705 is mapped into the upper megabyte of
Starting at the SRAM start address, the board design decodes a 128K byte segment accommodating
both the 80K byte display buffer and the S1D13705 internal register set. The S1D13705 registers are
mapped into the upper 32 bytes of the 128K byte segment (1FFE0h to 1FFFFh).
When using the S5U13705B00C board on a non-ISA bus system, system or external decode logic
must map the S1D13705 into an appropriate memory space.
and 0D0000h.
This memory space is in the first 1M byte of ISA bus memory and should be used if these
segments are not taken up by other devices such as network adapters, SCSI cards, or other
peripherals.
ISA bus memory, starting address of F00000h. To use this memory on an ISA bus system, the
system BIOS has to be configured to set a memory ‘hole’ starting at this address. Some systems
allow the user to configure the size of this hole and the starting address of where it begins while
others just allow a 1M byte hole at the top of the 16M byte memory space. This memory hole is
configured by entering the system CMOS Setup Utility. This memory space should be used if
segments 0Dh and 0Eh are being used by other devices or if a VGA display adapter is needed.

used while using the S5U13705B00C board at this memory address. A monochrome display
adapter, a terminal, or a non-VGA compatible display adapter must be used.
