2 16-BIT ISA BUS INTERFACE
S1D13503
X18A-G-003-05
For the purpose of the example shown below, the following conditions apply:
1.
2.
Note
This memory configuration will conflict with a VGA card installed on the same bus, therefore either a
serial terminal or monochrome display adapter is recommended as the primary console.
This section provides the necessary logic equations and settings to complete the interface between the S1D13503 and the
16-bit ISA Bus.
Note
A PAL was used instead of discrete logic to reduce external component count.
Indexed I/O with addresses 0310h and 0311h (see Configuration Options)
128Kbytes of display memory occupying $C and $D segments (see Configuration Options)
