10) Write data to RAM
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, and 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.
11) Read data from RAM
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 is 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 the case of DDRAM read operation, cursor shift instruction plays the same
role as DDRAM address set instruction; It also transfers RAM data to the output data register.
After read operation the address counter is automatically increased/decreased by 1 according to the entry
mode. After CGRAM read operation, display shift may not be executed correctly.
* In the case of RAM write operation, after this AC is increased/decreased by 1 like read operation. At this time,
AC indicates the next address position, but you can read only the previous data by the read instruction.
