Figure 5-16. Master Controller and Two Slave Controllers, Six Phases

In this configuration, the Master senses that there are two Slave controllers, and distributes a six-phase

CLKIO signal. The Slave controllers sense the voltage on their PHSEL pins, and delay the proper number

of CLKIO pulses to be 60

° or 120° out of phase with the Master.
