Processing contents
(1) The S.IENG instruction performs the following operation.
100
BW (E1 RL) (%)
RH RL
(2) Make setting to satisfy RH > RL.
(3) If RH  RL, the processing is executed unchanged but engineering value reverse conversion is not performed.
(4) If RH = RL, BW = 0.
Operation Error
In the following cases, the error flag (SM0) turns ON and the error code is stored in SD0.
