LTC1605-1/LTC1605-2
*************************************************************************
* This routine retrieves the LTC1605’s 16-bit data using two 8-bit
* reads. The BYTE input is manipulated through Port A’s Bit3. During
* the first read when BYTE is low, the upper byte is read and stored in
* DIN1.During the second read when BYTE is high, the lower byte is
* read and stored in DIN2.
