2.2.3 CLKoutX_DLY[3:0] -- Clock Output Delays
These bits control the delay stages for each clock output pin. In order for these delays to be active, the respective CLKoutX_MUX
(See 2.2.1) bit must be set to either "Delayed" or "Divided and Delayed" mode. By adding the delay block to the output path a fixed
delay of approximately 400 ps is incurred in addition to the delay shown in the table below.

2.2.4 CLKoutX_EN bit -- Clock Output Enables
This bit controls whether each clock output is enabled or not. If the EN_CLKout_Global bit (See 2.3.4) is set to zero or if GOE pin
is held low, all CLKoutX_EN bit states will be ignored and all clock outputs will be disabled.
