S1D13504 S5U13504B00C Rev.1.0 ISA Bus Evaluation Board User Manual
X19A-G-004-06 Issue Date: 01/02/02
2 Installation and Configuration
The S1D13504 has 16 configuration inputs MD[15:0] which are read on the rising edge of RESET#.
S1D13504 configuration inputs MD[5:1] are fully configurable on this evaluation board for different
host bus selections; one five-position DIP switch is provided for this purpose. All remaining config-
uration inputs are hard-wired. See the S1D13504 Hardware Functional Specification, document
number X19A-A-002-xx for more information.
When using the S5U13504B00C with the ISA bus, the following are the recommended settings.
The polarity of the Configuration DIP Switches is closed = 1 or high; open = 0 or low.
Closed = 1 or high; open = 0 or low.
