Byte 12: VCO Frequency Control Register
Note: The decimal representation of these 9 bits (Byte 12 bit
[7:0] & Byte 11 bit [7] ) + 8 is equal to the VCO divider value.
For example if VCO divider value of 36 is desired, user need
to program 36 - 8 = 28, namely, 0, 00011100 into byte 12 bit
& byte 11 bit 7.
