DIP slide switch S1A (EEPROM serial data connection to USB FX2 microcontroller)

DIP slide switches S1B and S1C (Mode PIN: selection of the way to program SPI Flash)

DIP slide switches S1D (Master Reset of TE0320)
DIP slide switches switch S1D is OFF by default, to allow the USB FX2 microcontroller and the FPGA to runoperate regularly.
- When DIP slide switches S1D is ON, the TE0320 is in reset state.
- When DIP slide switch is OFF, the TE0320 is in run (normal) state . If the TE0320 was in reset state before operates regularly (regular state).
During the transition from reset state (S1D ON for example) to regular state (S1F OFF), the USB FX2 microcontroller reload the serial EEPROM in RAM and the FPGA reload the bitstream from SPI Flash.
