„ B, C, U, V Inputs (synchronous mode)
At synchronous mode (ANS=1), C(channel status), U(user data) and V(validity) are input via 10pin header
(PORT3: BCUV). BLS is output at normal mode (TRANS=0), and is input at audio routing mode (TRANS=1). In
case of audio routing mode, BLS, C, U an V can be directly input from the AKD4114 via 10-line flat cable. The pin
layout of PORT3 is shown in Figure 2.

The AK4101A can be controlled by pins at synchronous mode (ANS=1) and by internal register at asynchronous
mode (ANS=0). Synchronous/Asynchronous mode is set as Table 7.

Default
At asynchronous mode (ANS=0), the AK4101A can be controlled via printer port (parallel port) of IBM-AT
compatible PC. Connect PORT6 (uP-I/F) with PC by 10-line flat cable packed with the AKD4101A-B. Take care of
the direction of connector. There is a mark at pin#1. The pin layout of PORT6 is shown in Figure 3.
