4. ES/EX/SS series MPU does not have M1083. During the execution of FROM/TO instruction, all external or
internal interruption subroutines will be forbidden. The interruptions are allowed only after FROM/TO instruction
finishes its execution. FROM/TO instruction can also be used in an interruption subroutine.
5. M1083 for switching instruction modes in SA/SX/SC/EH/EH2/SV series MPU:
a) When M1083 = Off, during the execution of FROM/TO instruction, all external or internal interruption
subroutines will be forbidden. The interruptions are allowed only after FROM/TO instruction finishes its
execution. FROM/TO instruction can also be used in an interruption subroutine.
b) When M1083 = On and an interruption signal occurs during the execution of FROM/TO instruction, the
interruption will be processed first (with a 100us delay) and the execution of FROM/TO will be stopped. After
the interruption subroutine finishes its execution, the program will jump to the next instructio of FROM/TO.
FROM/TO cannot be used in an interruption subroutine.
FROM/TO Application Example 1:
Adjust the A/D conversion curve of DVP-04AD. Set the OFFSET value of CH1 as 0V (= K0
LSB
) and GAIN value as
2.5V (= K2,000
LSB
).

1. Write H0 to CR#1 of anlog input module No. 0 and set CH1 as mode 0 (voltage input: -10V ~ +10V).
2. Write H0 to CR#33 and allow OFFSET/GAIN tuning in CH1 ~ CH4.
3. When X0 goes from Off to On, write the OFFSET value K0
LSB
into CR#18 and the GAIN value K2,000
LSB
into
