'oneToSet' means that in a bitwise fashion each write data bit of a one will set the corresponding bit in the field.  'oneToToggle' means that in a bitwise fashion each write data bit of a one will toggle the corresponding bit in the field. 'zeroToClear' means that in a bitwise fashion each write data bit of a zero will clear the corresponding bit in the field. 'zeroToSet' means that in a bitwise fashion each write data bit of a zero will set the corresponding bit in the field. 'zeroToToggle' means that in a bitwise fashion each write data bit of a zero will toggle the corresponding bit in the field. 'clear' means any write to this field clears the field. 'set' means any write to the field sets the field. 'modify' means any write to this field may modify that data. If this element is not present the write operation data is written.
