$01: 10bits Output Value X MSB (Read only)
Signed byte data (2’s complement): 0g = 10’h000
Reading low byte XOUTL latches high byte XOUTH to allow 10-bit reads.
XOUTH should be read directly following XOUTL read.
$02: 10bits Output Value Y LSB (Read only)
Signed byte data (2’s complement): 0g = 10’h000
Reading low byte YOUTL latches high byte YOUTH to allow coherent 10-bit reads.
YOUTH should be read directly following YOUTL.
$03: 10bits Output Value Y MSB (Read only)
Signed byte data (2’s complement): 0g = 10’h000
Reading low byte ZOUTL latches high byte ZOUTH to allow coherent 10-bit reads.
ZOUTH should be read directly following ZOUTL.
$04: 10bits Output Value Z LSB (Read only)
Signed byte data (2’s complement): 0g = 10’h000
Reading low byte ZOUTL latches high byte ZOUTH to allow coherent 10-bit reads.
ZOUTH should be read directly following ZOUTL.
$05: 10bits Output Value X MSB (Read only)
$06: 8bits Output Value X (Read only)
Signed byte data (2’s complement): 0g = 8’h00
$07: 8bits Output Value Y (Read only)
Signed byte data (2’s complement): 0g = 8’h00
