You might need to decouple/recouple different interfaces in a Reconfigurable Partition at different times. An example of this is to recouple the clock and reset inputs to a Reconfigurable Partition so that the Reconfigurable Module can be put into reset before the other interfaces are recoupled. The following figure shows this being handled with two independently controlled signals (decouple_early and decouple_late). Figure 2 shows this with one control signal and a two-clock cycle delay between the master decoupler and the slave decouplers.
