Note to Table 4–2:
(1) The MSEL0, MSEL1, and MSEL2 switches combine to specify a single device configuration. The default 0, 0, 0 combination corresponds to a
2.5 v passive serial configuration with the standard power-on-reset delay. For a complete list of MSEL combinations, refer to the
and Remote System Upgrades in Cyclone IV Devices
(2) The board ships with a simple design example stored in the EPCS flash memory device.To load the design and see the four user LEDs (D5-D8)
blink, set the S7.1 - S7.4 switches to on, off, on, on, and power cycle the board. These switch settings corresponds to a 2.5 V active serial
configuration with the standard power-on-reset delay. Source code for the EPCS design resides in the <install
dir>\kits\cycloneIVGX_4cgx15_starter\examples directory.

Switch 1 has the following options:
When on, the MSEL0 state is logic low.
■
When off, the MSEL0 state is logic high.
■
Switch 2 has the following options:
When on, the MSEL1 state is logic low.
■
When off, the MSEL1 state is logic high.
■
Switch 3 has the following options:
When on, the MSEL2 state is logic low.
■
When off, the MSEL2 state is logic high.
■
Switch 4 has the following options:
When on, the EPCS device defaults to disabled, but allows the MAX II
■
device to enable or disable the EPCS device.
When off, the EPCS_nCS signal floats, requiring the MAX II device to
■
enable or disable the EPCS device.
