This EZ-KIT is designed to demonstrate the ADSP-SC573 processor's capabilities. The board has a 25 MHz input
clock and runs at 450 MHzinternally.
User I/O to the processor is provided in the form of three pushbuttons and eight LEDs.
The software-controlled switches (SoftConfig) facilitate the switch multi-functionality by disconnecting the push-
buttons from their associated processor pins and reusing the pins elsewhere on the board.
Software-Controlled Switches (SoftConfig)
On the board, most of the traditional mechanical switches and jumpers have been replaced by I
led switches. The remaining mechanical switches are provided for the boot mode and pushbuttons. Reference any
