: Head number of the devices where the data to be added to/subtracted from is stored (BIN 16 bits)
:
Data for additing/subtracting or head number of the devices where the data for additing/subtracting is stored (BIN 16 bits)
:
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)
Function
BK+
(1) Adds n points of BIN data from the device designated by and n-points of BIN data from the device designated by
and stores the result from the device designated by onward.
(2) Block addition is performed in 16-bit units.
(3) The constant designated by can be between 32768 and 32767 (BIN 16-bit data).
(4) The following will happen when an underflow or overflow is generated in an operation result:
The carry flag in this case does not go ON.
