Transfer when Master is writing one byte to slave:
Transfer when Master is writing multiple bytes to slave:
Transfer when Master is receiving (reading) one byte of data from slave:
Transfer when Master is receiving (reading) multiple bytes of data from slave:
Data are transmitted in byte format (DATA). Each data transfer contains 8 bits. The number
of bytes transferred per transfer is unlimited. Data is transferred with the Most Significant bit
(MSb) first. If a receiver can’t receive another complete byte of data until it has performed
some other 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 LIS202DL 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:
