GrayToBin_** and BinToGray_**
The following example for the GrayToBin_BYTE instruction is for when In is BYTE#16#A5.
z BinToGray_**
The BinToGray_** instructions convert the bit string in data to convert In to a gray code. The conversion
procedure is as follows for when In and Out are BYTE data.
1 The most-significant bit (bit 7) of In is used as is as the most-significant bit (bit 7) of Out.
2 An exclusive logical OR is taken of the value of bit 7 in In and the value of bit 6 in In. The result
is used as bit 6 of Out.
3 This process is repeated through the least-significant bit (bit 0) of Out.
The following example for the BinToGray_BYTE instruction is for when In is BYTE#16#C6.
The name of the instruction is determined by the data types of In and Out. For example, if In and Out
are the WORD data type, the instruction is GrayToBin_WORD or BinToGray_WORD.
