clock edge. Because the address pointer auto-increments to the next address byte, it is possible to read multiple
bytes consecutively by continuing to pulse the Serial Clock line. An example set of commands to read from the y-
axis register is given below:
Note: Each SX bit is the same value as the most significant bit of the y-axis data.
To read from the FIFO buffer, a command byte to write to a data register (0x0A) must first be sent so that we can
configure the FIFO Control register (address 0x28) to indicate that we want the FIFO buffer to store data. After the
ADXL362 has been configured to use the FIFO buffer, a command byte to read from the FIFO buffer (0x0D) must
first be sent, then followed by pairs of data bytes containing which axis is being measured as well as the
acceleration data. An example set of commands to read from the FIFO buffer is given below:
Note: Each SX bit is the same value as the most significant bit of the y-axis data. b15 and b14 represent which axis the incoming data represents.
