2–8
The TLV320AIC10 has four serial-interface modes that support most modern DSP engines. This modes can be
selected by M0 and M1. In mode 0 (Figure 2–8), FS is one-bit wide and it is active high one SCLK period before the
first bit (MSB) of each data transmission. In modes 1 (Figure 2–9) and 2 (Figure 2–10), the TLV320AIC10 operates
as a slave to interface with an SPI master in which FS is the SPISEL that determines the sampling rate. SCLK needs
to be free-running. In mode 3 (Figure 2–11), FS is low during data transmission into DIN and DOUT.
