Display Control Instructions
Outline
Table 3 shows the instructions. Read/write (R/W) signal, data/instruction (D/I) signal, and data bus
signals (DB0 to DB7) are also called instructions because the internal operation depends on the signals
from the MPU.
These explanations are detailed in the following pages. Generally, there are following three kinds of
instructions:
1. Instruction to set addresses in the internal RAM
2. Instruction to transfer data from/to the internal RAM
3. Other instructions
In general use, the second type of instruction is used most frequently. Since Y address of the internal
RAM is increased by 1 automatically after writing (reading) data, the program can be shortened. During
the execution of an instruction, the system cannot accept instructions other than status read instruction.
Send instructions from MPU after making sure that the busy flag is 0, which is proof that an instruction is
not being executed.
