Frame-Sync (FS) Function—Master Mode
The master mode in the TLV320AIC11 is selected by connecting pin M/S pin to HI. In the master mode, the
TLV320AIC11 generates the frame-sync signal (FS) to the DSP that goes low on the rising edge of SCLK and remains
low during a 16-bit data transfer.

Frame-Sync (FS) Function—Slave Mode
The slave mode is selected by connecting pin M/S to LO. The frame-sync timing is generated externally by the master,
as shown in Figure 2–14 (that is, FSD) and is applied to FS of the slave to control the ADC and DAC timing.

NOTE: MP: master primary (master-device data is transferred during this period, the DOUT of the slave device is in high-impedance state).
SP: slave primary (slave device data is transferred during this period, the DOUT of master device is in high-impedance state).
MS: master secondary (master device control register information is transferred during this period, the DOUT of slave device is in high-
impedance state).
SS: slave secondary (slave device control register information is transferred during this period, the DOUT of master device is in high-
impedance state).
