【0x11 : Detection Switch-On】
Name:
DETECT_ON
Address: 0x11
Description:
This register indicates the change to ON from OFF of each switch.
If the mask for the ON operation included in the sensor settings is enabled, this register is disabled.
Logical OR of this register is ONDET included ‘Interrupt factor’ register.
1 : Detect On. 0 :Not detect On.

【0x14 : Interrupt of PWM continuous flashing】
Name:
DETECT_PWM_FINISH
Address: 0x14
Description:
This register indicates the end of the each LED PWM drive. And in the case that the PWM function is
stopped by the writing 0 to the PWM operation register (0xFC), this register is set to 1.
Logical OR of this register is PWM included ‘Interrupt factor’ register.
1 : Finished LED PWM drive. 0 :Clear.
