Figure 5. TLV2542 and TLV2545 Timing
using CS as the FS input
When interfacing the TLV2541 with the TMS320 DSP, the FSR signal from the DSP may be connected to the
CS input if this is the only device on the serial port. This saves one output terminal from the DSP. (Output data
changes on the falling edge of SCLK. This is the default configuration for the TLV2542 and TLV2545.)
