This instruction shows whether S6A0078 is in internal operation or not. If the resultant BF is high, it means the
internal operation is in progress and you have to wait until BF to be low, and then the next instruction can be
performed. In this instruction you can read also the value of address counter.

Write binary 8-bit data to DDRAM/CGRAM/SEGRAM.
The selection of RAM from DDRAM, CGRAM, or SEGRAM, is set by the previous address set instruction : DDRAM
address set, CGRAM address set, SEGRAM address set. RAM set instruction can also determines the AC direction
to RAM. After write operation, the address is automatically increased/decreased by 1, according to the entry mode.

Read binary 8-bit data from DDRAM/CGRAM/SEGRAM.
The selection of RAM is set by the previous address set instruction. If address set instruction of RAM is not
performed before this instruction, the data that read first is invalid, because the direction of AC is not determined. If
you read RAM data several times without RAM address set instruction before read operation, you can get correct
RAM data from the second, but the first data would be incorrect, because 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 transfer RAM data to output data register. After read operation address counter is automatically
increased/decreased by 1 according to the entry mode. After CGRAM/SEGRAM read operation, display shift may
not be executed correctly.
- In case of RAM write operation, after this AC is increased/decreased by 1 like read operation. In this time, AC
indicates the next address position, but you can read only the previous data by read instruction.
