There are two 4 bit DIP Switches on the TEBF0808 carrier board to configure options and set parameters. The table below describes the functionalities of the particular switches.
DIP-switch S4
Table below describes the functionalities of DIP-switch S4 at their each positions:
| DIP-switch S4 | Position ON | Position OFF | Notes |
|---|---|---|---|
| S4-1 | PUDC_B is Low | PUDC_B is HIGH | Internal pull-up resistors during configuration are enabled at ON-position, means I/O's are 3-stated until configuration of the FPGA completes. |
| S4-2 | x | x | not connected |
| S4-3 | SC CPLDs' JTAG enabled | SC CPLDs' JTAG disabled | JTAG interface is enabled on both SC CPLDs, as this CPLDs are configured in a casdaced JTAG chain. |
| S4-4 | DC-DC converter U18 (5V) enabled | DC-DC converter U18 (5V) not manually enabled | In OFF-position, the DC-DC-converter will be still enabled by the Enable-signal ('5V_EN') of SC CDPD U17 U39 (wired-OR circuit). |

DIP-switch S5
DIP-switch S5 located close to PWR push-button is connected to the two System Controller CPLDs, its functionalities depend on the current firmware of the CPLDs.
The switches of this DIP-switch have to be set in bit-patterns to set a parameter like boot mode or FMC_VADJ valueDIP-switch is connected to SC CPLD U17 and U39 as fellows:
| DIP-switch S5 | Signal Schematic Name | Connected to | Functionality | CPLD Documentation |
|---|---|---|---|---|
| S5-1 | SC_SW1 | SC CPLD U39, pin 133 | set 2-bit code for boot mode selection | Section: Boot Mode |
| S5-2 | SC_SW2 | SC CPLD U39, pin 138 | ||
| S5-3 | SC_SW3 | SC CPLD U17, pin 6 | user defined | |
| S5-4 | SC_SW4 | SC CPLD U17, pin 5 | set FMC_VADJ: 1.8V at ON-position, 1.2V at OFF-position |
Table 23: DIP-switch S5 connection to SC CPLDs
The boot mode of the mounted Ultrascale+ Zynq MPSoC modules will be set in current SC CPLD firmware version as fellow described in the table below:
| S5-1 | S5-2S5-3 | S5-4 | Description | |
|---|---|---|---|---|
| ON | ON | ON | ON | Default, boot from SD/eMMC, 1.8V FMC VADJmicroSD or SPI Flash if no SD is detected |
| ON | ON | x | xBoot from microSD, SD or SPI Flash | |
| OFF | ONx | x | Boot from eMMC | |
| ON | OFF | x | x | Boot mode PJTAG0 |
| OFF | OFFx | x | Boot mode main JTAG | |
| x | x | x | ON | FMC VADJ = 1.8V |
| x | x | x | OFF | FMC VADJ = 1.2V |

On-board LEDs
The TEBF0808 carrier board is equipped with several LED to signal current states and activities. The functionality of the LEDs D4 ... D7 depends on the current firmware of the SC CPLDs U17 and U39.
