This System on Module is designed to demonstrate the ADSP-21593 processor’s capabilities. The board has a 25
MHz input clock and runs at a max core clock frequency of 1GHz.
User I/O to the processor is provided in the form of two pushbuttons and three 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On the board, most of the traditional mechanical switches and jumpers have been replaced by I
2
C software-control-
led switches. The remaining mechanical switches are provided for the boot mode and pushbuttons. Reference any
SoftConfig*.c file found in the installation directory for an example of how to set up the SoftConfig feature of
