When Num=2, all bits of the value of In are shifted by two bits to the right and Bit0~Bit1 of In are
discarded and the value of Bit6~Bit7 are supplemented with 0 as shown in the following figure.
 Precautions for Correct Use
 The input variables are not allowed to omit. An error will occur during the compiling of the software
if any input variable is omitted. But the output variable is allowed to omit.
 When the value of Num is 0, the value of Out is the same as In.
 Programming Example
 The data types of SHR_In and SHR_Num are UINT and USINT respectively and their values are
300 and 3 respectively. The data type of Out1 is UINT and the value of Out1 is 37 when SHR_EN
is TRUE.
