Direct Configuration Mode
For DSP applications that use continuous data transfer mode for autobuffering, or for DMA operations that do not
have the capability to interfere with the data conversion channel by inserting the secondary communication, the
TLV320AIC11’s direct-configuration mode provides a flexible alternative to programming control registers through
pin DCSI. The serial input to DCSI should normally be in a high state, start its valid data with a start bit of logic low,
and pull high as a stop bit after transmission of the LSB. DCSI requires a pullup resistor for 3-state input. The AIC11
registers data bits on the falling edge of SCLK. Figure 3–8 shows a typical connection between the TMS320C54x
and the AIC11 using DCSI for direct configuration of control registers. Figure 3–9 shows the timing diagram for the
direct configuration mode.
