Entry Mode Set
ROM:
Switches the CGROM memory bank in the character mode (GR = 0). Uses bank 0 for display when
ROM = 0 and bank 1 for display when ROM = 1. For details, see the CGROM Bank Switching Function
section.
I/D:
Increments (I/D = 1) or decrements (I/D = 0) the DDRAM address by 1 when a character code is
written into or read from DDRAM. The cursor or blinking moves to the right when incremented by 1 and
to the left when decremented by 1. The same applies to the writing and reading of CGRAM and SEGRAM.
GR:
Activates the character mode when GR = 0. Displays the font pattern on CGROM or CGRAM
according to the character code written in DDRAM. Activates the graphics mode when GR = 1. Displays
a given pattern according to the bitmap data written in CGRAM. In this case, data in DDRAM is not used
for display. Segment pattern display set to SEGRAM is enabled both in the character mode and graphics
mode. For details, see the Graphics Display Function section.

Cursor Control
B/W
: When B/W is 1, the character at the cursor position is cyclically (every 32 frames) blink-displayed
with black-white inversion.
When B/W = 1 and LC = 1, all characters including the cursor on the display line appear with black-white
inversion. The characters do not blink. For details, refer to the Line-Cursor Display section.
C:
The cursor is displayed on the 8th raster-row when C is 1. The 6-dot cursor is ORed with the character
pattern and displayed on the 8th raster-row.
