5.4 Targets output status (Target Status)
The data message format for NRA15 system target output status is shown as in the table below.
The start sequence (0xAAAA) and termination sequence (0x5555) has been omitted for the
table, where the value of RollCount is continuously cycled between 0-1-2-3-0-1-2-3 ......
When the PC or an external MCU cannot process the output data of the NRA15 sensor in time,
it will cause the received RollCount value to be discontinuous. At this time a faster removal
methods should be found to solve this problem.
