Result from rotating all
bits of the original data by
the number of bits

Out
The data type of Out must be the same as In.
Note:
The symbol ● indicates that the parameter is allowed to connect to the variable or constant of the data type.
 Function Explanation
ROL is used to rotate all bits of the value of In by the number of bits specified by Num to the left and the
result is output to Out.
Via ROL, the bits shifted out of the left will shift to the null bits in the right one by one. When Num=2, all
bits of the value of In rotates by two bits to the left. The rotation method is that Bit0~Bit5 are shifted to
Bit2~Bit7 respectively, Bit 7 is shifted to Bit1 and Bit 6 is shifted to Bit0.
