If written to, RESERVED bits must be written to only 0
unless otherwise indicated.
Read back value of RESERVED bits and registers is
unspecified and should be discarded.
Recommended values must be programmed and
forbidden values must not be programmed where they
are indicated in order to avoid unexpected results.
