RATE DATA FORMAT
The ADXRS453 gyroscope transmits rate data in a 16-bit format
as part of a 32-bit SPI data frame. See Table 10 for the full 32-bit
format of the sensor data response. The rate data is transmitted
MSB first, from D15 to D0.

The data is formatted as a twos complement number with a scale
factor of 80 LSB/°/sec. Therefore, the highest obtainable value
for positive (clockwise) rotation is 0x7FFF (decimal +32,767),
and the highest obtainable value for negative (counterclockwise)
rotation is 0x8000 (decimal −32,768). Performance of the device
is not guaranteed above ±24,000 LSB (±300°/sec).
