4.7 Mask Compare (MSK)
Use this instruction to apply a bitĆmask to two variables and then have them compared
to determine if the values are equal.
While EN is true, the value of Mask is logically ANDED with the variables In1 and In2.
After applying the bitĆmask, the instruction then compares In1 and In2 to determine if
they are equal. If the variables are equal, Q is true.
In1, In2, and Mask are treated as unsigned integers. If any of these parameters is
converted to double integers, the most significant 16 bits are set to zero.
