3.2.1
The FC requests a secondary communication when it is asserted. The FC terminal is latched at the rising
edge of FS (primary communication), so FC should be pulled high before the rising edge of the primary frame
sync (FS). Figures 3–3 and 3–4 show the FS output from a master device.

3.2.2
The LSB of the DAC data within a primary transfer can request a secondary communication when the device
is in the 15-bit mode.
Software Secondary Serial Communication Request
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 and D1 is the least significant bit. Bit D0 is then used
for the secondary communication request control. All digital data values are in 2’s complement data format
(figure 3–5).
If the data format is set to the 16-bit word mode, all 16 bits are either ADC or DAC data and secondary
communication can then be requested only by hardware (FC terminal).
