2I NSTALLATION AND C ONFIGURATION
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 S19A-A-002-xx for more information.
When using the S5U13504P00C 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 .
