● Performs logical OR operation for the data of Sa and Sb when the operation control input "EN" =1 or "EN↑"
( P instruction) from 0 to 1. This operation compares the corresponding bits of Sa and Sb (B0~B15 or
B0~B31). The bit in the D is set to 1 if one of the corresponding of Sa or Sb is 1. The bit in the D is set to 0 if
both of the corresponding bits of Sa and Sb is 0.
