The VCO and reference divider select registers high (PNRH1 and
PNRH2) contain the programming information for the high byte of VCO
feedback divider, N, and reference divider, R.
VDSx_[11:8] — VCO Divider Select Bits
RDSx_[9:8] — Reference Divider Select Bits
The VDSx_[11:8] and RDSx_[9:8] bits are not latched until the
respective low bytes are written.
