Serial bus communication setting pin

When set to low: The 3-wire serial bus

signals are set as the input signals.

When set to high: The I

2C serial bus

signals are set as the input signals.

LED driver output type setting pin

When set to low: Constant-current output

is set for the LED driver.

When set to high: Open drain output is set

for the LED driver.

TEST

Test pin

This pin must always be connected to

GND.

SVCC

RESET

Reset signal input pin

Reset status when set to low.

SVCC

RT1

Reference current setting resistor

connection pin.

By connecting the external register between

this pin and GND, the reference current is

generated. The pin voltage is approximately

0.98V. By changing the current level, it is

possible to change the oscillator frequency

and LED driver current value (in the

constant-current mode).
