2 Installation and Configuration

The S1D13705 has four configuration inputs, CNF[3:0], which are read on the rising edge of RESET# and are fully configurable on this evaluation board. One six-position DIP switch is provided on the board to configure the four configuration inputs, select the S5U13705B00C memory/register start address, and enable/disable hardware power save mode.

The following settings are recommended when using the S5U13705B00C with the ISA bus.
