of other than 32-bit are considered a programming error and operation is undefined.

Reserved bits in the following register descriptions are not guaranteed to have predictable values. Software

must preserve the values of reserved bits when writing to a register. Also, when reading from a register,

software should not rely on the value of any reserved bit remaining consistent.
