BS2-0:
When SW = 1, they set the crystal display drive bias value within the range of 1/2 to 1/8 bias. The
liquid crystal display drive bias value can be selected according to its drive duty ratio and voltage. For
details, see the Liquid Crystal Display Drive Bias Selector Circuit section.

Entry Mode
REV:
Displays all character and graphics display sections except for the segment display section with
black-white reversal. For details, see the Reversed Display 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 the CGROM or CGRAM
according to the character code written in the DDRAM. Activates the graphics mode when GR = 1.
Displays a given pattern according to the bit map data written in the CGRAM. In this case, data in the
DDRAM is not used for display. Segment pattern display set to the SEGRAM is enabled both in the
character mode and graphics mode. For details, see the Graphics Display Function section.
