Example:
When X007 is ON, the 2’s complement value (sign inverted data) of BW39 is stored in D0122.
For example, if BW38 is 4660, the 2’s complement value -4660 is stored in D0122.
2’s complement data is calculated as follows.
Note:
- The data range of A is -32768 to 32767. If the data of A is -32768, the same data -32768
is stored in B.
