2. 32-bit operation (DBK- and DBK-P)
1) "2n" 32-bit binary data starting from [ +1, ] are subtracted from "2n" 32-bit binary data starting from
[ +1, ], and the operation result is stored in "2n" points starting from [ +1, ].
2) A (32-bit) constant from -2,147,483,648 to +2,147,483,647 can be directly specified in [ +1, ].

Caution
• When underflow or overflow occurs in the operation result, the following processing is executed. At this time, the
carry flag does not turn ON.
- In the case of 16-bit operation
- In the case of 32-bit operation
• Note that the 32-bit value [n+1, n] is valid when D or R is specified as "n" in a 32-bit instruction.
In the case of "DBK - D0 D100 D200 R0", "n" is [R1, R0].
Instruction Description
BK+ (FNC192) Adds binary block data.
K-32768(H8000) – K2(H0002) → K32766(H7FFE)
K32767(H7FFF) – K-2(HFFFE) → K-32767(H8001)
K-2,147,483,648(H80000000) – K2(H00000002) → K2,147,483,646(H7FFFFFFE)
K2,147,483,647(H7FFFFFFF) – K-2(HFFFFFFFE) → K-2,147,483,647(H80000001)
