LEDs and Push Buttons

Programmable Flag Push Buttons (SW10–13)

Four push buttons, SW10–13, are provided for general-purpose user input. The buttons connect to the PF0-3programmable flag pins of the proces- sor. The push buttons are active high and, when pressed, send a high (1) to the processor. Refer to “LEDs and Push Buttons” on page 1-13for more information on how to use the flags to program the processor. The push button enable switch (SW5) is capable of disconnecting the push but- tons from its corresponding PF signal (refer to “Push Button Enable Switch (SW5)” on page 2-11). The programmable flag signals and associ- ated switches are shown in Table 2-14.
