Write to a register using a mask
Write to register by masks allows you to operate through two masks and thus work at the
bit level on a register. The first mask performs a logical multiplication (AND) on the register
and the second one a logical addition (OR).
The AND mask indicates the bits of the register that will be modified. The bits that have the
value "1" in the mask will remain unchanged; while those that have a "0" will take this value.
The value that the bits that are going to be modified will take will be the value that said bits
have in the OR mask.
