8. LED current conversion
9. Slope process
・ The current of the LED driver to each Brightness is set up.
・ Although a table setup (initial value) is prepared
beforehand, it can change into a user setup by overwriting.
Bit ： IU*(6:0) (Back light)
・ Slope process is given to LED current to dim naturally.
・ The slope function is carried also in the driver for keys.
・ LED current changes in the 256Step gradation in slopeing.
・ UP(dark→bright ),Down(bright→dark) LED current transition
・ Back light current changes as follows at the time of a slope.
・ The slope method at the time of the change in Auto Luminous control mode and register setting mode.
・ LED current data can be read through I
speed are set individually.
TLH (THL) is a time setup of the current steps 2/256.
It can choose.
Once LED current is set to 0mA at Auto Luminous control mode at the
time of a change at the time of
MDCIR=1, it transits according to the slope time set up by TLH.
