Figure 13. TMS320 Interface
If there is no need to have more than one device on the serial bus, then CS can be tied low. Figure 14 shows
an example of how to connect the TLV5624 to TMS320, SPI
or Microwire using only three pins.

Notes on SPI
and Microwire: Before the controller starts the data transfer, the software has to generate a
falling edge on the I/O pin connected to FS. If the word width is 8 bits (SPI
and Microwire), two write
operations must be performed to program the TLV5624. After the write operation(s), the DAC output is updated
automatically on the next positive clock edge following the 16th falling clock edge.
serial clock frequency and update rate
The maximum serial clock frequency is given by:

The maximum update rate is:

+ 1.25 MHz
Note that the maximum update rate is just a theoretical value for the serial interface, as the settling time of the
TLV5624 has to be considered, too.
