Note:
Be sure the ST7070 is not in the busy state (BF = 0) before sending an instruction from the MPU to the ST7070.
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.
