Si1010/1/2/3/4/5
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 NSS bit is held low while continuing to send SCK
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 22.4 and a burst read in Figure 22.5. As long as
NSS is held low, input data will be latched into the transceiver every eight SCK cycles.
