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 4 and a burst read in Figure 5. As long as nSEL is held low, input data will be
latched into the Si4330 every eight SCLK cycles.
