function, it can hold the clock line, SCL LOW to force the transmitter into a wait state. Data
transfer only continues when the receiver is ready for another byte and releases the data line. If
a slave receiver doesn’t acknowledge the slave address (i.e. it is not able to receive because it
is performing some real time function) the data line must be left HIGH by the slave. The Master
can then abort the transfer. A LOW to HIGH transition on the SDA line while the SCL line is
HIGH is defined as a STOP condition. Each data transfer must be terminated by the generation
of a STOP (SP) condition.
In order to read multiple bytes, it is necessary to assert the most significant bit of the sub-
address field. In other words, SUB(7) must be equal to 1 while SUB(6-0) represents the
address of first register to read.
In the presented communication format MAK is Master Acknowledge and NMAK is No Master
Acknowledge.

SPI Bus Interface
The LIS3LV02DL SPI is a bus slave. The SPI allows to write and read the registers of the
device.
The Serial Interface interacts with the outside world with 4 wires:
CS
,
SPC
,
SDI
and
SDO
.
Figure 4.
Read & write protocol
CS
is the Serial Port Enable and it is controlled by the SPI master. It goes low at the start of the
transmission and goes back high at the end.
SPC
is the Serial Port Clock and it is controlled by
the SPI master. It is stopped high when
CS
is high (no transmission).
SDI
and
SDO
are
respectively the Serial Port Data Input and Output. Those lines are driven at the falling edge of
SPC
and should be captured at the rising edge of
SPC
.
Both the Read Register and Write Register commands are completed in 16 clock pulses or in
multiple of 8 in case of multiple byte read/write. Bit duration is the time between two falling
edges of
SPC
. The first bit (bit 0) starts at the first falling edge of
SPC
after the falling edge of
CS
while the last bit (bit 15, bit 23, ...) starts at the last falling edge of SPC just before the rising
edge of
CS
.
bit 0
: RW bit. When 0, the data DI(7:0) is written into the device. When 1, the data DO(7:0) from
the device is read. In latter case, the chip will drive
SDO
at the start of bit 8.
bit 1
: MS bit. When 0, the address will remain unchanged in multiple read/write commands.
When 1, the address will be auto incremented in multiple read/write commands.
bit 2-7
: address AD(5:0). This is the address field of the indexed register.
