Signed byte data (2’s compliment): Zero G = 10’h000
Reading low byte XOUTL latches high byte XOUTH to allow 10-bit reads.
XOUTH should be read directly following XOUTL read.
Signed byte data (2’s compliment): Zero G = 10’h000
Reading low byte XOUTL latches high byte XOUTH to allow 10-bit reads.
XOUTH should be read directly following XOUTL read.
Signed byte data (2’s compliment): Zero G = 10’h000
Reading low byte YOUTL latches high byte YOUTH to allow coherent 10-bit reads.
YOUTH should be read directly following YOUTL.
Signed byte data (2’s compliment): Zero G = 10’h000
