Note: *1

There are two INT_EN bits in the control register. When one bit changes, the other bit also changes at the

same time.

STOP

: Stops lux measurement after the current ADC cycle. The lux data measured last is retained. The ADC

enters standby mode.(1: Stop)

INT_COUNT

: How many times the upper or lower threshold value is exceeded in succession before an interrupt

signal is generated.

(00: Once; 01: 4 times; 10: 8 times; 11: 16 times)

INT_AT_RT

: Automatic restoration from interrupt enable/disable

(0: Processing automatically restored; 1: Processing not automatically restored (restored after the

interrupt is cancelled by the system))

INT_EN

: Interrupt enable/disable (0: Disable interrupts; 1: Enable interrupts)
