Use Index byte write.
For N programming, the user only needs to access Byte 12, Byte 13, and Byte 10.

CPU[2:0], SRC[7,5:1],
PCI[3:0], PCIF[1:0]
Write Byte 12 for CPU PLL N, CPU f = N* Resolution (see resolution table).
Write Byte 13 for SRC PLL N, SRC f = N*0.666667, PCI = SRC f /3.
Enable N Programming bit, Byte 10 bit 1. Once this bit is enabled, any N value will be changed on the fly.
