Note: All registers are set to 0 when the LC74788/M/JM is reset by the RST pin.
Blinking in reverse video mode switches the display between
normal character display and reverse video display.
Erasing RAM takes about 500 s. (This operation
must be executed in the DSPOFF state.)
Valid in external synchronization mode when
character display is off.
The registers are reset when the CS pin is low, and
the reset state is cleared when CS is set high.
