Contrast ADJ (CA) set
D7
—: don’t care
This instruction is for adjusting the liquid crystal display voltage.
(1) D3 to D0 (CT3 to CT0) (Contrast adjustment value setting bits)
When FH is written to these bits, the liquid crystal display voltage (voltage between the V
0
and V
SS
pins) becomes
a maximum.
When 0H is written, the liquid crystal display voltage becomes a minimum.
By setting the values from 0H to FH, the liquid crystal display voltage can be adjusted just like an electronic
volume control.
These bits are all reset to “0” if the
RESET
pin is pulled to a “L” level.
