See the following example that the Word data In is converted to the Byte data Out. The values
of Bit0~Bit7 of In are copied and pasted to Bit0~Bit7 of Out. And the values of Bit8~Bit15 of In
are not converted and have no impact on the conversion.
 The Bit-string data are converted into the Bit-string data as the following table shows.

 Bit string to Integer
 The Bit-string data can be converted to the Integer data. And some instructions are shown
below.
The rule for the conversion of bit-string data into integer data is consistent with that for the
conversion of bit-string data into bit-string data.
The less-length data is converted to the greater-length data by writing the values of all bits of
