ADSP-SC589 EZ-Board® Evaluation System Manual
27
The ADSP-SC589 EZ-Board has two 25 MHz input clocks and runs at a max core clock frequency of
450 MHz. The input clock frequency can be changed through the SI5356A I2C programmable clock
generator.
3.2 Software-Controlled Switches (SoftConfig)
On the ADSP-SC589 EZ-Board, most of the traditional mechanical switches have been replaced by
I2C software-controlled switches. The remaining mechanical switches are provided for the boot mode
and push buttons. Reference any SoftConfig*.c file found in the installation directory for an example
of how to set up the SoftConfig feature of the ADSP-SC589 EZ-Board through software.
The SoftConfig section of this manual serves as a reference to any user that intends to modify an
existing software example. If software provided from ADI is used, there should be little need to
reference this section.
Care should be taken when changing SoftConfig settings not to create a conflict with
interfaces. This is especially true when connecting extender cards.
