Synchronized Operation as a Master and Slave Unit
Two XRP7714s can be synchronized together. This Master-Slave configuration is described below.
"    Master
When the XRP7714 powers up as a master unit after the internal configuration memory is loaded
the unit will send CLK_OUT and SYNC_OUT signals to the slave on the preconfigured GPIO pins.
"    Slave
When powering in sync mode the slave unit will initially power up with its internal clock to transfer
the configuration memory. Once this transfer occurs, then the unit is set to function as a slave unit.
In turn the unit will take the external clock provided by the master to run as its main internal clock.

External Clock Synchronization Master Slave combination
When an external clock is used, the user will need to setup the master to also have an external
clock in function. All of the same rules apply as in the External clock synchronization, Synchronized
operation as a Slave unit section of this document. There are two ways of synchronizing this,
either the external clock going to both Master/Slave CLK_IN, or CLK_IN can go to the Master, and
the Master can synchronize SYNC_OUT and CLK_OUT to the Slave.
