Program CDCM6208 in pin programmable mode through a CPLD

Hi,

    I would like to change the clock frequency as I want after the system begins running. Can I configure it in pin programmable mode?If yes,  could you recommend a hardware configuration.

    Or, I can only achieve it by SPI or I2C mode.

Thanks.

    Hi,

    Programming via I2C/SPI is not available in Pin Mode. In Pin mode, the state of the control pins determines the configuration of the device for all device states. Pages 36-41 of the datasheet has information on supported configurations in Pin Mode.

    Regards
