Preliminary Technical Data ADAR1000 SPI BLOCK WRITE MODE
Data can be written to the SPI registers in a Block Write Mode, where the register address will be automatically incremented, and data for consecutive registers can be written without sending new address bits. Data writing can be continued indefinitely until CSB is raised again, ending the write process. Figure 5 Timing Diagram for Block Write Mode Rev.
