„ Serial Control
The AK4645 can be controlled via the printer port (parallel port) of IBM-AT compatible PC. Connect PORT4
(CTRL) with PC by 10 wire flat cable packed with the AKD4645. When I²C bus mode is used, PORT4 should be
directly connected to the I²C bus on the system. JP3, 17 and 12 should be set to I²C bus mode to control the AK7830.
