Chapter 4: Application Examples
(1) For parameters and positions that are 32 bits, the value needs to be spread over two 16 bit
words. The high word will contain the most significant 16 bit and the low word will contain the
least significant 16 bits.
Example: If the scale factor was 4096, the high word would be 0 (0 hex) and the low
word would be 4096 (1000 hex).
Example: If the scale factor was 500,000, the high word would be 7 (7 hex) and the low
word would be -14,288 (A120 hex).
(2) The following is an example program for setting up the 1746R Resolver Interface Module.
