User Buttons

The target PSoC 64 board contains a user button (SW2) connected to the P0[4] pin on the PSoC 64
chip. This button can be used for general user inputs or for wakeup during Hibernate mode.
The board has a reset button and mode select button. The reset button (SW1) is connected to the
XRES pin of the PSoC 64 device and is used to reset the device. The mode select button (SW3) is
connected to the PSoC 5LP device for programming mode (Refer to the
details). All the buttons connect to ground on activation (active LOW).
