4. Write the desired data to the register pointed to by the MAP.
5. If the INCR bit (see Section 4.9.1) is set to 1, repeat the previous step until all the desired registers
are written, then bring CS
high.
6. If the INCR bit is set to 0 and further SPI writes to other registers are desired, it is necessary to bring
CS
high, and follow the procedure detailed from step 1. If no further writes to other registers are de-
sired, bring CS
high.
