[AKD4589-B]
„ Jumper setting
[JP1] (GND): Analog grand and digital grand
Open: Analog grand and digital grand are separated.
Short: Analog grand and digital grand are common. “DGND” jack is able to open at this time. < Default>
„ Operation of toggle switch.
[SW1](PDN): Reset for AK4589.
AK4589 should be reset once after power-on of AKD4589-B.
Set SW1 (PDN) “L” once for power down of AK4589 after power-on of AKD4589-B.
And then set SW1 (PDN) “H”.
Keep “H” during operation of AK4589.
„ Indication of LED
It turns on each pin when each pin output is “H”.
[LE1] (INT0): Indicate of AK4588’s INT0 pin output.
[LE2] (INT1): Indicate of AK4588’s INT1 pin output.
„ Serial Control
AK4589 can be controlled via the printer port (parallel port) of IBM-AT compatible PC.
Connect printer port (parallel port) of PC and PORT1(uP-I/F) of AKD4589-B by 10 wire flat cable(packed with
AKD4589-B).
Take care of the direction of 10 pin connector and 10 pin header.
(The red line side of 10 wire flat cable of 10-pin connector should be connected to 5 and 6 pin of 10pin header.)
