A. Hitachi mode performs asynchronous operations that do not require an external LCD_MEMORY_CLK. The first
LCD_MEMORY_CLK waveform is only shown as a reference of the internal clock that sequences the other signals.
The second LCD_MEMORY_CLK waveform is shown as E1 because the LCD_MEMORY_CLK signal is used to
implement the E1 function in Hitachi mode.
