Si4313-B1
The SPI interface contains a burst read/write mode, which allows for reading/writing sequential registers without
having to resend 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 shown in Figure 4, and a burst read is shown in Figure 5. As long as nSEL is held low, input data will
be latched into the Si4313 every eight SCLK cycles.
