IN
OUT
The AK4184A’s register (GPIO Pin Direction Register) should be set GPIO pins as input.
Select “L” or “H” on S1, the AK4184A’s register should be read from the Pin Level Register. The pin state is
detected.
(3-2) GPIO pin as output port
AKD4184A evaluates GPIO control function with LED (GP0~GP7).
Set up the jumper pins.

The AK4184A’s register (GPIO Pin Direction Register) should be set GPIO pins as output.
The AK4184A’s register (GPIO Pin Set/Clear Register) should be set pin level to “H”. Therefore, LED
(GP0~GP7) turns on.
(4) LED dimmer control function.
AKD4184A evaluates LED dimmer control on LED9 and LED10.
Set up the jumper pin.
JP18
PWM
(Short)
The AK4184A’s register (PWM Control Register) should be set to power up.
The AK4184A’s register should be changed by Bright Control Value. Therefore, LED9 and LED10 dimmer is
controlled.
