AryShiftRegLR
The AryShiftRegLR instruction shifts Size array elements of array of bit strings InOut[] to the left when
ShiftL changes to TRUE. The shift operation starts from InOut[0]. Input value In is inserted to the least-
significant bit. The most-significant bit of the array of bit strings is output to the Carry (CY) Flag (P_CY).
When ShiftR changes to TRUE, the bits are shifted one bit to the right and In is inserted to the most-sig-
nificant bit. The least-significant bit of the array of bit strings is output to the Carry (CY) Flag (P_CY).
When Reset is TRUE, P_CY and all of the bits in Size elements starting from InOut[0] are set to FALSE.
The following example is for when InOut is BYTE data, Size is UINT#2 and ShiftL changes to TRUE.
