The data being sent from the Accelerometer Board can be viewed in three formats using the Raw Data
application. See AN3231, MC1320x/MC1321x Demonstration Operation, Running the Basic Packet
Error Rate, Wireless UART, Accelerometer, Range, Test Mode, and Lighting Demonstration Applications
for more information about the Raw Data application. The Raw Data application presents the raw data sent
from the accelerometers and processed by the MCU as follows:
