Figure 4. SPI Timing—READ Mode  
The SPI interface contains a burst read/write mode which allows for reading/writing sequential registers without  
having to re-send the SPI address. When the nSEL bit is held low while continuing to send SCLK pulses, the SPI  
interface will automatically increment the ADDR and read from/write to the next address. An example burst write  
transaction is illustrated in Figure 5 and a burst read in Figure 6. As long as nSEL is held low, input data will be  
latched into the Si4430/31/32 every eight SCLK cycles.
