Notes:

1. PWD = Power on Default

2. The power on default for byte 13-20 depends on the harware (latch inputs FS[0:4]) or I

Be sure to read back and re-write the values of these 8 registers when VCO frequency change is desired for the first

pass.

3. If Byte 8 bit 7 is driven to "1" meaning programming is intended, Byte 21-24 will lose their default power up value.
