[Example] When performing control by calling up data in Memory area 3 of CH1
1.
The memory area number, “3” is written to the memory area transfer (08DCH).
Data in Memory area 3 is called up to the CH1 register addresses.

2.
Control of CH1 is performed by using data in the register addresses.
If the memory area transfer (08DCH to 091BH) and the setting memory area number
(386CH to 38ABH) are set to the same memory area number, the respective data can be
synchronized.
Values in the control areas (095CH to 0E5BH) and the setting memory area number
(38ACH to 3DABH) are set to the same memory area number, the respective data can
be synchronized.
If data in the control area is changed, data in the memory area is also changed.
If data in the memory area is changed, data in the control area is also changed.
Data mapping function
When using a COM-ML joined to function modules, the data mapping function cannot be used.
