Figure 13. Initializing the PLL through the Serial Port
NOTE: It may not be convenient to control the ENB or CLK pins during power up per the Pin Descriptions. If this is the case, the part may
be initialized through the serial port as shown in the figure above. The sequence is similar to accessing the registers except that the
CLK must remain high at least 100 ns after ENB is brought high. Note that 3 groups of 5 bits are needed.
