SPI WRITE COMMANDS
Master processors write to the control registers, one byte
at a time, using the bit sequence shown in Figure 11. Some
configurations require writing both bytes to a register, which
takes two separate 16-bit sequences, whereas others require
only one byte. The programmable registers in Table 7 provide
controls for optimizing sensor operation and for starting vari-
ous automated functions. For example, to start an automatic
bias null sequence, set GLOB_CMD[0] = 1 by writing 0xBE01
to the SPI transmit register of the master processor, which feeds
the DIN line. The process starts immediately after the last bit
clocks into DIN (16

SPI READ COMMANDS
Reading data through the SPI requires two consecutive 16-bit
sequences, separated by an appropriate stall time (see Figure 2).
The first sequence transmits the read command and address on
DIN, and the second receives the resulting data from DOUT. The
7-bit register address can represent either the upper or lower byte
address for the target register. For example, when reading the
GYRO_OUT register, the address can be either 0x04 or 0x05.
Figure 13 provides a full-duplex mode example of reading the
GYRO_OUT register. In addition, the second SPI segment sets
the device up to read TEMP_OUT on the following SPI segment
(not shown in Figure 13).
