5.4.8 WSFL (FNC 37)
Operation:
The instruction copies n
2 source devices to a word
stack of length n
1. For each addition of n2 words, the
existing data within the word stack is shifted n
2words
to the left. Any word data moving to a position
exceeding the n
1 limit is diverted to an overflow area.
The word shifting operation will occur every time the
instruction is processed unless it is modified with
either the pulse suffix or a controlled interlock.
Note: when using bit devices as source (S) and
destination (D) the Kn value must be equal.
