F15_XCHRedundant instruction
This is a redundant instruction. It is replaced by: FP_EXCHANGE
The contents in the 16-bit areas specified by d1 and d2 are exchanged if the trigger EN is in the ON-state.
Output
16-bit area to be exchanged with d2
16-bit area to be exchanged with d1
Instead of using this F instruction, we recommend using the corresponding FP7 instruction: FP_EXCHANGE
The variables d1 and d2 have to be of the same data type.
