The function of the toggle SW
SW1 (PDN): Resets the AK4707. Keep "H" during normal operation.
The indication content for INT pin
Changes of the 08H status can be monitored via the TEST1 (INT). The INT pin is the open drain output and goes "L" for 2µs (typ.) when the status of 08H is changed.
Serial Control
The AK4707 can be controlled via the printer port (parallel port) of IBM-AT compatible PC. Connect PORT1 (CTRL) with PC by 10-line flat cable packed with the AKD4707-A. The control software packed with this evaluation board supports I2C control only.
