2.2 User I/O – Switches and LEDs
User Push Buttons: SW1 – SW6: 7015/20/30 SOM
When a 7015/20/30 SOM is plugged in, the carrier provides 5 PL and 1 PS user GPIO push
buttons for the Zynq-7000 AP SoC (blue and green in the table below). When a 7010 SOM is
attached, only two switches are available - SW1 (PL_PB1) and SW6 (PS_PB1). These are
highlighted in the table as green.
Each signal has a pull down resistor and noise decoupling capacitor to help reduce switch
bounce. When depressed the button provides a logic high on the respective net. The switches
are placed in a North, South, East, West and Center position. This is to allow the customer to
better distinguish which button to press.
Below figure shows the locations of the user switches and the associated labeling. These
switches are located in the upper left corner of the PZCC-FMC-V2 board.
