Не могу понять... не по русски написано:
Read binary 8-bit data from DDRAM/CGRAM.
The selection of RAM is set by the previous address set instruction. If the address set instruction of RAM is not
performed before this instruction, the data that has been read first is invalid, as the direction of AC is not Yet
determined. If RAM data is read several(???????) times without RAM address instructions set before read operation, the
correct RAM data can be obtained from the second. But the first data would be incorrect, as there is no time
margin to transfer RAM data.
In case of DDRAM read operation, cursor shift instruction plays the same role as DDRAM address set instruction,
it also transfers RAM data to output data register.
After read operation, address counter is automatically increased/decreased by 1 according to the entry mode.
After CGRAM read operation, display shift may not be executed correctly.
NOTE: In case of RAM write operation, AC is increased/decreased by 1 as in read operation.
At this time, AC indicates the next address position, but only the previous data can be read by the read
instruction.
