predict - used to define what would be the value of the register (as per attributes) when we are trying to write the value mentioned as arguement.Would update the RAL copy of the register value, but does not touch the actual register.
get - would return of RAL value of the register.
set - would set the RAL value of the register, irrespective of attributes.
This is just a very brief decription. Please refer to the source code for actual details.
Note: As per my understanding, perdict does not return the value. Just returns success or failure.
