FIFO ENTRIES REGISTERS
Z-AXIS DATA REGISTERS
These registers indicate the number of valid data samples
present in the FIFO buffer. This number ranges from 0 to 512
or 0x00 to 0x200. FIFO_ENTRIES_L contains the least significant
byte. FIFO_ENTRIES_H contains the two most significant bits.
Bits[15:10] of FIFO_ENTRIES_H are unused (represented as X
= don’t care).
These two registers contain the sign extended (SX) z-axis
acceleration data. ZDATA_L contains the eight LSBs, and
ZDATA_H contains the four MSBs of the 12-bit value.
The sign extension bits (B[15:12], denoted as SX in the
ZDATA_H bit map that follows) have the same value as the
MSB (B11).

Address: 0x13, Reset: 0x00, Name: ZDATA_H
TEMPERATURE DATA REGISTERS
These two registers contain the sign extended (SX) x-axis
acceleration data. XDATA_L contains the eight least significant
bits (LSBs), and XDATA_H contains the four most significant
bits (MSBs) of the 12-bit value.
These two registers contain the sign extended (SX) tempera-
ture sensor output data. TEMP_L contains the eight LSBs, and
TEMP_H contains the four MSBs of the 12-bit value. The value is
sign extended; therefore, Bits[B15:B12] of TEMP_H are all 0s or
all 1s, based on the value of Bit B11.
The sign extension bits (B[15:12], denoted as SX in the
XDATA_H bit map that follows) have the same value as the
MSB (B11).
The sign extension bits (B[15:12], denoted as SX in the TEMP_H
bit map that follows) have the same value as the MSB (B11).

Address: 0x0F, Reset: 0x00, Name: XDATA_H
Y-AXIS DATA REGISTERS
Address: 0x14, Reset: 0x00, Name: TEMP_L
Address: 0x15, Reset: 0x00, Name: TEMP_H
SOFT RESET REGISTER
These two registers contain the sign extended (SX) y-axis
acceleration data. YDATA_L contains the eight LSBs and
YDATA_H contains the four MSBs of the 12-bit value.
Address: 0x1F, Reset: 0x00, Name: SOFT_RESET
Writing Code 0x52 (representing the letter, R, in ASCII or
unicode) to this register immediately resets the ADXL362. All
register settings are cleared, and the sensor is placed in standby.
Interrupt pins are configured to a high output impedance mode
and held to a valid state by bus keepers.
The sign extension bits (B[15:12], denoted as SX in the
YDATA_H bit map that follows) have the same value as the
MSB (B11).
Address: 0x10, Reset: 0x00, Name: YDATA_L
This is a write-only register. If read, data in it is always 0x00.
Address: 0x11, Reset: 0x00, Name: YDATA_H
