address set instruction,it also transfers RAM data to output data register.
In case of DDRAM read operation,cursor shift instruction plays the same role as DDRAM
DDRAM stores display data of maximum 80x8 bits(80 characters).
DDRAM address is set in the address counter(AC) as a hexadecimal number
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.
