25 Block Data Operation – FNC190 to FNC199
25.1 FNC192 – BK+ / Block Data Addition
2. 32-bit operation (DBK+ and DBK+P)
1) "2n" 32-bit binary data starting from [
+1, 
] are added to "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].
