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.

4.4.7Reset Push Button (SW8)

The RESET push button resets all of the ICs on the board. This reset does not affect the USB interface chip (U11) unless communication has not been initialized with a PC. After USB communication has been initialized, the only way to reset the USB is by powering down the board.
