Figure 26. Dead Time Addition
Additional dead time can be added by the addition of a dead time
resistor from Vref to CT. See text on Oscillator section for more
information.

Figure 27. External Clock Synchronization
The sync pulse fed into the clock pin must be at least 3.9 V. RT and CT
need to be set 10% slower than the sync frequency. This circuit is also
used in Voltage Mode operation for master/slave operation. The clock
signal would be coming from the master which is set at the desired
operating frequency, while the slave is set 10% slower.
