4.4.6Programmable Flag Push Buttons (SW4, SW5, SW6, SW7)

Four push buttons are provided for general-purpose user input. SW4-7 connect to the DSP’s Programmable Flag (PF) pins, PF4-7. The push buttons are active high and when pressed send a high (1) to the DSP. Refer to section 3.6 for more information about the use of the PFs when programming the DSP. Table 4-5shows the PF signal and the switch it is connected to.
