Green LED D22 indicates presence of 3.3V power from the SoM attached.

3.6 4-bit DIP-switch S3

There is a 4-bit DIP-switch S3 with following default settings:

Switc

h

Functionality

S3-1

CM1: Mode pin 1 (routed to System Controller CPLD).

S3-2

CM0: Mode pin 0 (routed to System Controller CPLD).

S3-3

JTAGEN: Set to ON for normal JTAG operation. Has to be set to OFF position for System

Controller CPLD JTAG access.

S3-4

 MIO0: Pin from/to JB1-88 and PMOD (J1) connector. Direction depends on Module FPGA/

SoC configuration.

3.7 User Push-buttons

On the TE0701 Carrier Board there are two push-buttons (S1 and S2) and are routed to the System Controller CPLD

and available to the user. The default mapping of the push-buttons is as follows:

Nam

e

Default Mapping:

S1

Custom Button functionality CPLD Firmware dependent.

S2

If S2 is pushed, the active-high Power ON (PON) signal (that is internally pulled-up) will be

de-asserted, which can be considered as a "RESTART" function as all on-module power

supplies will be switched off (except 3.3VIN) on button push and back on again on button

release.

The active-high PON signal is directly mapped to the active-high EN1 signal which is

routed to the module's System Controller CPLD (e.g., on the TE0720) and directly used as a

mandatory active-high enable signal to the power FET switch, enabling on-module 3.3V

power supply output as well as all other DC-DC converters on the module.

Table 2: Description of default functions of user push-buttons S1 and S2.

The function of the push-buttons depend on the System Controller CPLD firmware. For detailed information of the

function of the push-buttons, please refer to the documentation of the TE0701 System Controller CPLD.

LED5 (D5) to LED8 (D8) are operating only when the corresponding power supply VIOTB (i.e., bank 1 of the

on-board System Controller CPLD) is switched on. This can be accomplished by connecting the FMC power

supply FMC_VADJ to VIOTB (J21: 1,2-3), which is the default option, or by connecting either 2.5V (J17: 1,

2-3) or 3.3V (J17: 1-2,3) to VIOTB (J21: 1-2,3). Please note that for the first default option, the FMC power

please refer to the documentation of the TE0701 System Controller CPLD.
