DS3170DK DS3/E3 Single-Chip Transceiver Design Kit
User Input Switch (SW3)
SW3 is an 8-pin DIP switch that controls the function of the on-board microcontroller and the two on-board FPGAs,
and offers a number of generic inputs for user programs.

FUNCTION
Generic Input-Only Pin to the General-Purpose FPGA. Value of pin is copied to general-
purpose register XXXXXXXX. Can be used for user programs. This pin has no effect if FPGA
ENABLE is logic 0.
Generic Input-Only Pin to the General-Purpose FPGA. Value of pin is copied to general-
purpose register XXXXXXXX. Can be used for user programs. This pin has no effect if FPGA
ENABLE is logic 0.
Input-Only Pin to the General-Purpose FPGA (U3). When this pin is logic 1 (SW3.3 is OFF),
the FPGA is enabled and will transfer data from the DS3170 and FPGA as directed from the
on-board microcontroller. When this pin is logic 0 (SW3.3 is ON), the FPGA is disabled. All
inputs and outputs to the DS3170 and port FPGA are tri-stated. Note: This pin does not cause
a hardware enable for the PORT FGPA.
Input-Only Pin to the General-Purpose FPGA (U3). When this pin is logic 1 (SW3.4 is OFF),
the DS3170 and the port FPGA are set up such that they use the 16-bit bus from the on-board
microcontroller. When this pin is logic 0 (SW3.4 is ON), the DS3170 and the port FPGA are set
up such that they use the 8-bit bus from the on-board microcontroller. This pin has no effect if
FPGA ENABLE is logic 0.
Input-Only Pin to the On-Board Microcontroller. When this pin is logic 1 (SW3.5 is OFF), the
on-board microcontroller loads the firmware from an external source rather than the internal
flash bank. When this pin is logic 0 (SW3.5 is ON), the microcontroller loads the firmware from
the internal flash bank. If you choose to load code from an external source, refer to the user
manual for the on-board microcontroller (U2) to ensure that all the timing and data are correct
to run this program. This option should only be used by the advanced user.
Input-Only Pin to the On-Board Microcontroller. Not implemented with the firmware shipped
from Dallas Semiconductor. This pin can be used by a user program.
Input/Output Pin to the General-Purpose FPGA (U3). This pin has an LED (DS4) to track the
value of this signal. This pin has no effect if FPGA ENABLE is logic 0. Note: If you choose to
use this as an output, USER INPUT 1 (SW3.7) must be in the off position.
Input/Output Pin to the General-Purpose FPGA (U3). This pin has an LED (DS5) to track the
value of this signal. This pin has no effect if FPGA ENABLE is logic 0. Note: If you choose to
use this as an output, USER INPUT 1 (SW3.8) must be in the off position.
