9.1 Description of command
Display is controlled by writing data into the instruction register and 13 data registers. The RS signal distinguishes the
instruction register from the data registers. 8-bit data is written into the instruction register with RS=1, and the code of data
register is specified. After that, the 8-bit data is written in the data register and the specified instruction is ex ecuted with RS=0.
During the ex ecution of the instruction, no new instruction can be accepted. Since the busy flag is set during this, read the busy
flag and make sure it is 0 before writing the nex t instruction.
