GrayToBin_** and BinToGray_**
z GrayToBin_**
The GrayToBin_** instructions convert the gray code in date to convert In to a bit string. 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 6 in In and the value of bit 7 in Out. The result
is used as bit 6 of Out.
3 This process is repeated through the least-significant bit (bit 0) of Out.
GrayToBin_**: Converts a gray code to a bit string.
BinToGray_**: Converts a bit string to a gray code.
