„ B, C, U, V Inputs and output
B(block start), C(channel status), U(user data) and V(validity) are inputted via 10pin header (PORT3: BCUV).
When BCU_IO bit is set to “1”, they are input signals. And when BCU_IO bit is set to “0”, they are output signals.
In parallel mode, they are fixed to output signals. Pin arrangement of PORT3 has become like Figure 3.

„ Serial control
The AK4115 can be controlled via the printer port (parallel port) of IBM-AT compatible PC. Connect the included
10pin cable to PORT6 (uP-I/F) of the AKD4115-A. Take care of the direction of connector. There is a mark at
pin#1. And the pin layout of PORT6 is as Figure 4 shows.
