Operands

Operand	Description
S	The first operand. Entries are only WORD data registers. These are the data registers to add to each other. The signed value range for each data register is -32,768 ~ 32,767 (216). The unsigned value range for each data register is 0 ~ 65,535 (216-1). The Hexadecimal value range for each data register is H0000 ~ HFFFF.
D	The second operand. Entries are only DWORD data registers. This is where the sum is saved.
n	The third operand. Entries are WORD data registers or constants. This is the number of data registers to sum starting at the data register S. The value range is 1 ~ D data register amount.

Notice

Error Flag (F11.0) Notice

The error flag, F11.0, will be ON for one scan when the address of the data register assigned by @D exceeds the range of the data register, D. The range of the data register, D, is dependent on the CPU type.
F11.0 turns ON when the value, n, exceeds the corresponding data register, S.

Important

The WSUM or WSUMP instructions will not execute if the value of n is less than 1 or greater than the amount of D data registers.
