February 11, 2012 Veton Këpuska 2 BF533 EZ-Kit Lite The EZ-KIT Lite provides  four (4) push buttons and  six (6) LEDs for general-purpose IO. 4 SW push-button switches The four general-purpose push button switches are labeled SW4  through SW7. A status of each individual button can be read through  programmable flag (PF) inputs: PF8 through PF11.  A PF reads 1 when a corresponding switch is being pressed-on. When  the switch is released, the PF reads 0.  A connection between the push button and PF input is established  through the SW9 DIP switch. 6 LEDs The six LEDs, labeled LED4 through LED9, are accessed via some of  the general-purpose IO pins of the flash memory interface.

February 11, 2012 Veton Këpuska 5 Push Button Enable Switch (SW9) Positions:  1 through 4 : disconnect the drivers associated with the push buttons from the PF pins of the  processor. 5 and 6 : are used to connect the transmit and receive frame syncs and clocks of SPORT0. This is  important when the AD1836 video decoder and the processor are communicating in I 2 S mode.  Table 2-6 shows which PF is driven when the switch is in the default (ON) position.
