Bit7 :
WPWMEN
External PWM Input “WPWMIN” terminal Enable Control (Valid/Invalid)
“0” : External PWM input invalid
“1” : External PWM input valid
Refer to “(11) Current Adjustment” of “The explanation of ALC” for detail.
Bit6 :
WPWMPOL
Polarity setting of External PWM input "WPWMIN" terminal
“0” : External PWM ’L’ drive
“1” : External PWM ’H’ drive
Refer to “(11) Current Adjustment” of “The explanation of ALC” for detail.
Bit [5:4] : (Not used)
Bit3 :
W6MD
LED6 control setting (individual / Main group)
“0” : LED6 individual control
“1” : LED6 Main group control
Refer to “LED Driver” for detail.
Bit2 :
W5MD
LED5 control setting (individual / Main group)
“0” : LED5 individual control
“1” : LED5 Use (Main group)
Refer to “LED Driver” for detail.
Bit1 :
W4MD
LED4 movement setting (unuse / use)
“0” : LED4 unuse
“1” : LED4 use (Main group Control)
Refer to “LED Driver” for detail.
Bit0 :
MLEDMD
Main group setting (Normal / ALC)
“0” : Main group Normal Mode(ALCNon-reflection)
“1” : Main group ALC Mode
Refer to “(1) Auto Luminous Control ON/OFF” of “The explanation of ALC” for detail.
Set up a fixation in every design because it isn't presumed W*PW that it is changed dynamically.
And, do the setup of W*PW when each LED is Off.
