Feature Descriptions
GPIO DIP Switch
Figure 1-27 shows the GPIO DIP switch circuit.
Table 1-30 lists the GPIO DIP switch connections to XC7Z045 AP SoC U1.
User PMOD GPIO Headers
[Figure 1-2, callout 26]
The ZC706 evaluation board GPIO 2 x 6 male headers J57 and J58 support Digilent Pmod
Peripheral Modules. J57 pins (IIC_PMOD_[0:7]) are connected to the TI TCA6416APWR I2C
expansion port device U16. J58 pins (PMOD1_[0:7]) are connected to the TI TXS0108E
3.3V-to-VADJ level-shifter U40.
See the Digilent website for information on Digilent Pmod Peripheral Modules [Ref 35].
Information about the TCA641APWR and TXS0108E devices is available at the Texas
Instruments website [Ref 26].
