[Figure 1-2, callout 22]
Switch SW4 grounds the XC7Z020 SoC PROG_B pin when pressed. This action clears
programmable logic configuration, which the PS software can then act on. The
FPGA_PROG_B signal is connected to XC7Z020 SoC U1 pin T11.
See the 7 Series FPGAs Configuration User Guide (UG470) [Ref 8] for further details on
configuring the 7 series FPGAs.
Figure 1-27 shows SW4.
