TE0320 is provided with 4 system DIP slide switches as shown in Figure 32: S1A, S1B, S1C, S1D.
Figure 32: DIP slide switches S1[A : D].
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 | 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.
