Typical Applications Circuit, Dual Mode 9.1.3.2 Multiple Devices In a multiple device system, it is often desirable to synchronize the clocks each device to minimize input ripple current as well as radiated and conducted emissions. This is accomplished by designating one of the controllers as the master and the other devices as 'slaves. The master generates the system clock, CLKIO, and it is distributed to the slaves. This is the most useful configuration of multiple devices and the one that is demonstrated in this data sheet. It is described in more detail in the Clock Master, PHSEL, and CLKIO Configurations section.
