„ The function of the toggle SW
[SW1] (PDN): Resets the AK4708. 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 AK4708 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 AKD4708-A. The control software packed with this evaluation board
supports I²C control only.
