These requirements are for successful FPGA configuration in SPI mode, where the FPGA provides the CCLK frequency. The post
configuration timing can be different to support the specific needs of the application loaded into the FPGA and the resulting clock source.
Subtract additional printed circuit board routing delay as required by the application.
