REGISTERS
1. If written to, RESERVED bits must be written to 0 unless otherwise indicated.
2. Read back value of RESERVED bits and registers is unspecified and should be discarded.
3. Recommended values must be programmed and forbidden values must not be programmed where they are
indicated in order to avoid unexpected results.
4. If written to, registers indicated as Reserved must have the indicated default value as shown in the register
map. Any other value can cause unexpected results.
