PCI Express Interface Controller
The fields of the PCI Express IP block core clock ratio register are described in
As an example of programming PEX_GCLK_RATIO, consider the case where the actual PCI Express
controller clock is 250 MHz, the ratio of the actual clock to the default clock (333 MHz) is 3:4. that is, the
default core clock has to be multiplied by the ratio (3/4, which is equivalent to 12/16). So the register has
to be programmed with the decimal numerator value 12 or 0x0000_000C.

The numerator of the ratio of the actual PCI Express controller clock frequency used to the
default core clock frequency of 333 MHz. The denominator of the ratio is fixed at 16.
The default value of this register is 0x10 (16 decimal), which corresponds to a ratio of 1:1 (or
16/16)
