Figure 1–1. Dual-Word (Telephone Interface) Mode
When the DATA-DR/CONTROL input is tied to a logic signal source varying between 0 and 5 V, the
TLC32046 is in the dual-word (telephone interface) mode. This logic signal is routed to the DR line for input
to the DSP only when data frame synchronization (FSD) outputs a low level. The FSD pulse duration is 16
shift clock pulses. Also, in this mode, the control register data bits D10 and D11 appear on D10OUT and
D11OUT, respectively, as outputs.
