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 desired, bring CS high.
