Note:  
Be sure the ST7066U is not in the busy state (BF = 0) before sending an instruction from the MPU to the  
ST7066U. If an instruction is sent without checking the busy flag, the time between the first instruction and next  
instruction will take much longer than the instruction time itself. Refer to Instruction Table for the list of each  
instruction execution time.
