S1 : the minuend
S2 : the subtrahend
D : the difference
When X20 = “OFF” → “ON”, the subtrahend (D1) will be subtracted from the minuend (D0), and the difference will
be stored at the destination device (D2).
When the result of an operation stores in the and it is equal to “0”, the Addition / Subtraction Zero Flag M9020
turns “ON”.
When the result of an operation exceeds 32,767, the Carry Flag M9022 turns “ON”.
When the result of an operation is less than -32,768, the Borrow Flag M9021 turns“ON”.
When X20 = “ON”, the instruction will subtract (D3, D2) from (D1, D0) and store the difference in (D5, D4).
