This instruction shows whether KS0066U is in internal operation or not.
If the resultant BF is “High”, internal operation is in progress and should wait BF is to be LOW, which by
then the nest instruction can be performed. In this instruction you can also read the value of the address
counter.
Write binary 8-bit data to DDRAM/CGRAM.
The selection of RAM from DDRAM, and CGRAM, is set by the previous address set instruction
(DDRAM address set, CGRAM address set).
RAM set instruction can also determine the AC direction to RAM.
After write operation. The address is automatically increased/decreased by 1, according to the entry

Read binary 8-bit data from DDRAM/CGRAM.
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.
