Description
LED[0] control: bits [2:0] correspond to {red, green, blue} partial
LEDs of the onboard LD0. If a bit is 1, appropriate internal LED is
illuminated.
LED[1] control (onboard LD1).
LED[2] control (onboard LD2).
LED[3] control (onboard LD3).
Description
LED[0] control: corresponds to the onboard LD4. If a bit is 1, LED
is illuminated.
LED[1] control (onboard LD5).
Description
BTN status: bits [3:0] correspond to {BTN3, BTN2, BTN1, BTN0}
onboard push buttons. For details refer to the Xilinx AXI GPIO IP
documentation.
