TE0320 is provided with 4 system DIP slide switches as shown in the figure below: S1A, S1B, S1C, S1D.
Please note the 4 switch labels are on one side and the <ON> label is on the opposite side.
DIP slide switches S1[A:D] condition the value of some system signals as described in the table below.
switch | S1 label | signal name | <OFF> | <ON> |
---|---|---|---|---|
S1A | 1 | EEPROM serial data connection to USB FX2 microcontroller | the USB FX2 microcontroller CANNOT read / write the serial EEPROM | the USB FX2 microcontroller can read / write the serial EEPROM |
S1B | 2 | M2 | mode pin M2 = 1 | M2 = 0 |
S1C | 3 | M1 | mode pin M1 = 1 | M1 = 0 |
S1D | 4 | /MR (master reset) | module reset | module running |
DIP slide switches S1A is ON by default, to allow the USB FX2 microcontroller to read the serial EEPROM and enumerate as a custom/specific USB device.
Mode pins M2 (S1B), M1 (S1C), M0 tell the FPGA how the bitstream will be loaded. See this section for more information.
DIP slide switches S1D is OFF by default, to allow the USB FX2 microcontroller and the FPGA to run
