Figure 8. SPI MULTIPLE-BYTE BURST TRANSFER
READING AND WRITING IN BURST MODE
Burst mode is similar to a single-byte read or write, except that CE is kept high and additional SCLK
cycles are sent until the end of the burst. The clock registers and the user RAM can be read or written in
burst mode. When accessing the clock registers in burst mode, the address pointer wraps around after
reaching 1Fh (9Fh for writes). When accessing the user RAM in burst mode, the address pointer wraps
around after reaching 7Fh (FFh for writes).
