Read and Write commands provide access to on-chip registers. After a Read command, the addressed data
can be clocked out the SDO pin by SCLK. After a Write command, 24 bits of write data must follow. The data
is transferred to the addressed register after the 24
of 32 addresses each. To access a desired page, write its number to the Page register at address 31.
