n Serial control mode
The AK4363 can be controlled via the printer port (parallel port) of IBM-AT compatible PC. Connect PORT2
(CTRL) with PC by 10-line flat cable packed with the AKD4363.
There are two modes: 3-wire serial & I2C bus. JP4 should be shorted at 3-wire serial control mode.
Chip address can be selected by SW2(MODE)-No.1(CAD1) and No.2(CAD0).
n Other jumper pins set up

Open: Separated <default>
Short: Common (The connector “DGND” can be open.)
[JP2](5V-3V): DVDD of AK4363 and power supply to logic
Open: Independent <default>
Short: Same (The connector “3V” should be open.)
