Notes:
1. Any register not listed here is reserved and must not be written.The result of a read operation on these registers is
undefined.
2. Except where noted, reserved register bits always read back as "1", and are not affected by write operations. For future
compatibility, it is recommended that prior to a write operation, registers should be read. Then the values read from the
RSVD bits should be written back unchanged during the write operation.
