Operands:

m: Address in the file register to be read D: Device for storing the read data (starting from the designated D)

n: Number of data read at a time

Explanations:

1. Range of m: K0 ~ K1,599 (SA/SX/SC); K0 ~ K9,999 (EH/EH2/SV)

2. Range of D: D2000 ~ D4999 (SA/SX/SC); D2000 ~ D9999 (EH/EH2/SV)

3. Range of n: For 16-bit instruction K1 ~ K1,600 (SA/SX/SC), K1 ~ K8,000 (EH/EH2/SV); For 32-bit instruction

K1 ~ K800 (SA/SX/SC), K1 ~ K4,000 (EH/EH2/SV)

4. See the specifications of each model for their range of use.

5. Flag: M1101. See explanations below.

6. SA/SX/SC/EH/EH2/SV uses this instruction to read the data in file registers and store them into data registers.

7. SA/SX/SC offers 1,600 16-bit file registers.

8. m and n of SA/SX/SC do not suppot E and F index register modification.

9. EH/EH2/SV offers 10,000 16-bit file registers.

10. If m, D and n fall without their range, operation error will occur. M1067, M1068 = On and D1067 will record the

error code H’0E1A.

Program Example 1:

1. The 16-bit instruction MEMR reads 100 data at address 10 in the file register and store the read data in register

D starting from D2000.

2. When X0 = On, the instruction will be executed. When X0 = Off, the instruction will not be executed and the

previously read data will remain unchanged.

MEMR K10 D2000 K100

Program Example 2:

1. The 32-bit instruction DMEMR reads 100 data at address 20 in the file register and store the read data in

2. When X0 = On, the instruction will be executed. When X0 = Off, the instruction will not be executed and the

previously read data will remain unchanged.
