These requirements are for successful FPGA configuration in BPI 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.
The initial BYTE# timing can be extended using an external, appropriately sized pull-down resistor on the FPGA’s LDC2 pin. The resistor
value also depends on whether the FPGA’s HSWAP pin is High or Low.
MultiBoot re-configuration starts on the rising edge after MBT is Low for at least the prescribed minimum period.
