NHD-0220BZ
Set DDRAM address to AC.
This instruction makes DDRAM data available form MPU.
When 1-line display mode (N=LOW), DDRAM address is form “00H” to “4FH”.
In 2-line display mode (N=High), DDRAM address in the 1
In the 2
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 if 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 mode.
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.
