... Semiconductor 12. Instruction Code The instruction code is defined as the signal through which the MSM6262-xx is accessed by the CPU. MSM6262-xx starts its operation upon receipt of the instruction code. The internal processing operation starts with a timing that does not affect the LCD display, so, the busy condition is longer than that of cycle time. ...
