n DIP switch (SW2) set up
n Serial control mode
The AK4364 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 AKD4364. 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

n The function of the toggle SW (SW1) Upper-side is "H" and lower-side is "L".
SW1 (-PD): Resets the AK4364. Keep "H" during normal operation.
n The indication content for LED
LED1 (VERF): Monitors VERF pin of the CS8414. LED turns on when some error has occurred to CS8414. LED2 (PREM): Indicates whether the input data is pre-emphasis or not. LED turns on when the data is pre-emphasised.
