1-3 Instructions for Data Transmission
During th e internal o peration of the system, da ta is transmit ted rapidly a nd incessa ntly
between memories or registers. This fast and incessant transmission is the power of system
capability. SH6610 system provides several instructions for data transmission, as follows:
Instruction: LDI
Function: to load Immediate Data I to “Accumulator” and “Data
Memory”
Format:
Instruction Code:
Carry Flag:
Operation:
LDI Mx I
01111 iiii xxx xxxx
Not affected
AC , Mx Å I
Explanation
LDI is a very freque ntly used inst ruction. It loads immediate d ata I to accu mulator a nd
data memory. However, due to this 4-bit system, the preset range of the imme diate data I is
00H ~ 0FH(0 ~ 15), and that of Mx is 00H~7FH.
[ Example ]
LDI 20H 05H
after execution:
AC=05H
Content of data memory $20H=05H
Programming Tip
There isn’t any specially defined register for users in SH6610 system, but we can use its
powerful data memory as registers in our program designing. In the above example, I have
used data memory $20H for a register. However, if they are expressed only by address and
without respective names, the design of the program will be very confusing. Here’s a tip for
you: you can use the pseudo-instruction EQU to define each data address.
AAA
Name of memory variable
EQU 2 0H
Pseudo-
Data memory address
Therefore, the LDI instruction can also be written like this:
LDI AAA 05H

Instruction: ADCM
Format:
Instruction Code:
Carry Flag:
Operation:
Explanation
Function: to add up the value of Data Memory, Carry Flag and the
value of Accumulator, and then save the result in both the
Accumulator and the Data Memory
ADCM Mx bbb
00000 1bbb xxx xxxx
CY
AC , Mx Å Mx + AC + CY
Instruction ADCM ad ds up the value of dat a memory , ca rry flag and the value of
accumulator, and saves the result in both the accumulator and the data memory. The ADCM
operation affects the carry flag: wh en the result of ADCM exceed s 0FH, the carry flag is set
to1; otherwise the value of CY is 0. Therefore we can decide whether there’s a carry by the
value of the carry flag after addition.
[ Example ] 05H +06H , CY=1
: ;CY=1
LDI 20H,05H ;$20H=05H,AC=05H
