Measurement data of magnetic sensor X-axis/Y-axis/Z-axis
HXL[7:0] bits: X-axis measurement data lower 8-bit
HXH[15:8] bits: X-axis measurement data higher 8-bit
HYL[7:0] bits: Y-axis measurement data lower 8-bit
HYH[15:8] bits: Y-axis measurement data higher 8-bit
HZL[7:0] bits: Z-axis measurement data lower 8-bit
HZH[15:8] bits: Z-axis measurement data higher 8-bit
Measurement data is stored in two’s complement and Little Endian format. Measurement range of each axis
is -32752 to 32752 in 16-bit output.
