TE0630 Configuration Switches: settings for USB Firmware, FPGA bitstream programming and Power Supply.
On-board 4xDIP switch S1 used for system and user settings.
Switch S1A is used to connect the USB controller to the IIC serial EEPROM:
Turn S1A on when programming the USB EEPROM (storing the USB vendor ID and device ID).
TE USB FX2 module is powered on when S1A is turned off: this will force the USB controller to provide its default (Cypress) vendor ID and device ID.
Switch S1B is used to control DC-DC converters:
Switches S1C and S1D can be used as user switches. Switches are active-low. Pull-up resistors should be defined in user constrains file (UCF) to use this switches in FPGA design. See the table below for details
Signal name | FPGA pin | Switch |
IO_L61_N_1 | AB21 | S1C |
IO_L63_N_1 | AA22 | S1D |
