Result from rotating all
bits of the original data by
the number of bits
specified by Num to the
right
Depends on the data type of the

Function Explanation
ROR is used to rotate all bits of the value of In by the number of bits specified by Num to the right and the
result is output to Out .
Via ROR, the bits shifted out of the right will shift to the null bits in the left one by one. When Num =2, all
bits of the value of In rotates by two bits to the right. The rotation method is that Bit2~Bit7 are shifted to
Bit0~Bit5 respectively, Bit0 is shifted to Bit6 and Bit1 is shifted to Bit7.
