„ Serial control
The AKD4358-B can be controlled via the printer port (parallel
port) of an IBM-AT compatible PC. Connect PORT2(uP-I/F) to the
PC with the 10-wire flat ribbon cable packed with the AKD4358-B.
Pay attention to the direction of the 10pin header. There is a mark
at 1pin. The pin layout of PORT2 is shown in Figure 2. Proper
connection makes the flat ribbon cable going away from the board.
„ Interface with AC3 decoder
PORT3(AC3) is used for interface with an AC3 decoder.
MCLK, BICK, LRCK and 4-line serial data can be input from
the decoder via PORT3. Pin layout of PORT3 is shown in
Figure3.
„ EXT Interface
PORT4(EXT) is used for interface with external device.
MCLK, BICK, LRCK and SDATA can be input from DSP or
decoder via PORT4. Pin layout of PORT4 is shown in
Figure4.
„ Interface with DSD decoder
PORT5(DSD_port) is used for interface with DSD
decoder. Pin layout of PORT5 is shown in Figure5.
