8. Write Display Data:
(Execution time: 6
μ
s) After the code $“0C” is written into the instruction register
with RS = 1, 8-bit data with RS = 0 should be written into the data register. This data is transferred to the
RAM specified by the cursor address as display data or character code. The cursor address is increased by 1
after this operation.

9. Read Display Data:
(Execution time: 6
μ
s) Data can be read from the RAM with RS = 0 after writing
code $“0D” into the instruction register. Figure 1 shows the read procedure.
This instruction outputs the contents of data output register on the data bus (DB0 to DB7) and then
transfers RAM data specified by the cursor address to the data output register, also increasing the cursor
address by 1. After setting the cursor address, correct data is not output at the first read but at the second
one. Thus, make one dummy read when reading data after setting the cursor address.
