7.6.5 Register Read and Write

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 24th data bit is received. Registers are organized into pages

of 32 addresses each. To access a desired page, write its number to the Page register at address 31.
