Serial Control
The AK4644 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 AKD4644. When I2C bus mode is used, PORT4 should be
directly connected to the I2C bus on the system. JP13,14 and 15 should be set to I2C bus mode to control the
AK7830.
