Software Secondary Serial Communication Request
The LSB of the DAC data within a primary transfer can request a secondary communication through bit D0 of control
register 1 when the device is in the 15-bit mode.
For all serial communications, the most significant bit is transferred first. For a 16-bit ADC word and a 16-bit DAC word,
D15 is the most significant bit and D0 is the least significant bit. For a 15-bit DAC data word in a primary
communication, D15 is the most significant bit, D1 is the least significant bit. Bit D0 is then used for the secondary
communication request control. All digital data values are in 2s-complement data format (see Figure 3–7).
If the data format is set to 16-bit word, all 16 bits are either ADC or DAC data, and secondary communication can
only be requested by hardware (FC terminal), or control registers can be programmed by the direct configuration
mode.

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
TLV320AIC10s 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 AIC10
registers data bits on the falling edge of SCLK. Figure 3–8 shows a typical connection between the C54x and the
AIC10 using DCSI for direct configuration of control registers. Figure 3–9 shows the timing diagram for the direct
configuration mode.
