FIFO ENTRIES 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).

Address: 0x0C, Reset: 0x00, Name: FIFO_ENTRIES_L

Address: 0x0D, Reset: 0x00, Name: FIFO_ENTRIES_H

X-AXIS 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.

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).

Address: 0x0E, Reset: 0x00, Name: XDATA_L

Address: 0x0F, Reset: 0x00, Name: XDATA_H

Y-AXIS DATA REGISTERS

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.

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

Address: 0x11, Reset: 0x00, Name: YDATA_H

Z-AXIS DATA REGISTERS

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: 0x12, Reset: 0x00, Name: ZDATA_L

Address: 0x13, Reset: 0x00, Name: ZDATA_H

TEMPERATURE DATA REGISTERS

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 TEMP_H

bit map that follows) have the same value as the MSB (B11).

Address: 0x14, Reset: 0x00, Name: TEMP_L

Address: 0x15, Reset: 0x00, Name: TEMP_H

SOFT RESET REGISTER

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

Interrupt pins are configured to a high output impedance mode

and held to a valid state by bus keepers.

This is a write-only register. If read, data in it is always 0x00.
