SUM
S : Starting number of source register
N : Number of registers to be summed
(successive N data units starting from S)
D : The register which stored the result (summation)
S, N, D, can associate with V, Z, P0~P9 index register to
serve the indirect addressing application.

z
When operation control “EN”=1 or “EN
↑
” (
P
instruction) changes from 0
→
1, it puts the successive N units of
16bit or 32 bit (
D
instruction) registers for addition calculation to get the summation, and stores the result into
the register which is designated by D.
z
When the value of N is 0 or greater than 511, the operation will not be performed.
z
Communication port1 or port2 can be used to serve as a general purpose ASCII communication interface. If
the data error detecting method is Check-Sum, this instruction can be used to generate the sum value for
sending data or ot use this instruction to check if the received data is error or not.
〈
Example 1
〉
When M1 changes from OFF
→
ON, following instruction will calculates the summation for 16-bit data.

The left illustrates that 6 16-bit registers starting from R0
is calculated for summation, and the result is stored into
the R100 register.
R0=0030H
R1=0031H
R2=0032H
R3=0033H
R4=0034H
R5=0035H
〈
Example 2
〉
When M1 is ON, it calculates the summation for 32-bit data.

The left illustrates that three 32-bit registers starting
from DR0, is calculated for their summation, and the
result is stored into the DR100 register.
