CNF2
The S1D13705 uses CNF3 through CNF0 and BS# to allow selection of the bus mode and other
configuration data on the rising edge of RESET#. Refer to the “S1D13705 Hardware Functional
Specification”, document number X27A-A-001-02 for details.
The tables below show those configuration settings important to the Generic #2 host bus interface.
The NEC VR4102/VR4111 provides the internal address decoding necessary to map to an external
LCD controller. Physical address 0A000000h to 0AFFFFFFh (16M bytes) is reserved for an external
LCD controller.
The S1D13705 supports up to 80K bytes of display buffer memory and 32 bytes for internal
registers. Therefore, the S1D13705 will be shadowed over the entire 16M byte memory range at
128K byte segments. The starting address of the display buffer is 0A000000h and register 0 of the
S1D13705 (REG[00h]) resides at 0A01FFE0h.
The NEC VR4102/VR4111 has a 16-bit internal register named BCUCNTREG2 located at address
0B000002h. It must be set to the value of 0001h to indicate that LCD controller accesses use a non-
inverting data bus.
The 16-bit internal register named BCUCNTREG1, located at address 0B000000h, must have bit
D[13] (ISA/LCD bit) set to 0 to reserve the 16M bytes space, 0A000000h to 0AFFFFFFh, for LCD
use and not as ISA bus memory space.
Test utilities and Windows
code is available for both the test utilities and the drivers.
The test utilities are configurable for different panel types using a program called 1375CFG, or by
directly modifying the source. The Windows
OEM for different panel types, resolutions and color depths only by modifying the source.
