19.1 FNC140 – WSUM / Sum of Word Data
Outline
This instruction calculates the sum of consecutive 16-bit or 32-bit data.
When calculating the addition data (sum value) in units of byte (8 bits), use the CCD (FNC 84) instruction.
→ For CCD (FNC 84) instruction, refer to Section 16.5.

Explanation of function and operation
1. 16-bit operation (WSUM and WSUMP)
The sum of "n" 16-bit data starting from is stored as 32-bit data in [ +1, ].
2. 32-bit operation (DWSUM and DWSUMP)
The sum of "n" 32-bit data starting from [ +1, ] is stored as 64-bit data in [ +3, +2, +1,
].
Operand type Description Data type
Head device number storing data whose sum is calculated 16- or 32-bit binary
Head device number storing sum 32- or 64-bit binary
