1) Asynchronous reset
2) Reset command
DVI is I
is supplied. In DVI 'L' term, internal state is set to Power Down mode.
1) Recommended Timing chart1 for VCC and DVI supply.
2) Timing chart2 for VCC and DVI supply.
All registers are reset. It is necessary on power supply sequence. Please refer "Timing chart for VCC and DVI power
supply sequence" in this page. It is power down mode during DVI = 'L'.
Reset command is for only reset Illuminance data register. (reset value is '0') It is not necessary even power supply
sequence. It is used for removing previous measurement result. This command is not working in power down mode, so
that please set the power on mode before input this command.
(If DVI rises within 1µs after VCC supply)

C bus reference voltage terminal. And it is also asynchronous reset terminal. It is necessary to set to 'L' after VCC
CC
and DVI power supply sequence
Reset Term ( more than 1µs )
Don't care state
ADDR, SDA, SCL is not stable if DVI 'L' term (1µs) is not given by systems.
In this case, please connect the resisters (approximately 100kOhm) to ADDR without directly
connecting to VCC or GND,
because it is 3 state buffer for Internal testing.
Reset Term (more than 1µs)
6/16
