Note: When instruciton 1 is a clear display instruction, adjust the transfer rate so that the 8th bit of instruction 2
is transferred after execution of the clear display instruction.
Note: Two bytes of the RAM read data after the start byte are invalid. The HD66740 starts to read the correct
RAM data from the third byte.
