6.2 Arithmetic Operation Instructions
BIN 16-bit data block addition and subtraction operations
BK+(P), BK-(P)
■BK+
• Adds n points of BIN data from the device designated by (S1) and n-points of BIN data from the device designated by (S2)
and stores the result to the area starting from the device designated by (D).
• Block addition is performed in 16-bit units.
• The constant designated by (S2) can be between -32768 and 32767 (BIN 16-bit data).
• The following will happen when an underflow or overflow is generated in an operation result: The carry flag (SM700) in this
case does not turn ON.
(S1): Head number of the devices where the data to be added to/subtracted from is stored (BIN 16 bits)
(S2): Data for adding/subtracting or head number of the devices where the data for adding/subtracting is stored (BIN 16 bits)
(D): Head number of the devices where the operation result will be stored (BIN 16 bits)
n: Number of addition/subtraction data blocks (BIN 16 bits)
