SBAS625A – SEPTEMBER 2013 – REVISED SEPTEMBER 2013

Standalone Operation

In standalone mode, as shown in Figure 105, each device has its own SPI bus. The serial clock can be

continuous or gated. The first CS falling edge starts the operation cycle. Exactly 24 falling clock edges must be

applied before CS is brought high again. If CS is brought high before the 24th falling SCLK edge, or if more than

24 SCLK falling edges are applied before CS is brought high, then the input data are incorrect. The device input

addressed registers as well. In order for another serial transfer to occur, CS must be brought low again.

Figure 106 and Figure 107 show write and read operations in standalone mode.
