7.5.1.2 Data Counters
The Data Counters request is used to read the value of the data counters in the AMIS49587. It contains one byte which is
used to know whether the counters must be reset or not (00: no reset, 01: reset) after reading them out.
There are 6 counters coded on 4 bytes each, which indicates:
1. number of CRC OK frames received
2. number of CRC not OK frames received
3. number of repeated frames
4. number of transmitted frames
5. number of corrected frames (with option Pad Correcting)
6. number of frames with bad Frame Indicator received

7.5.1.3 DataStats
The DataStats request is used to read the value of the current data statistics in the AMIS49587. The request contains one
byte which is used to know whether the counters must be reset or not (00: no reset, 01: reset) after reading them out.
If the AMIS49587 is synchronized the counters consist of 30 bytes:
1. The value of signal and noise (S0, N0, S1, N1) for the last subframe received (4 * 2 bytes) + the method and gain
used to demodulate this subframe (2 * 1 byte)
2. The method, gain and SNR (S0/N0, S1/N1) on the 5 last time slots in reception mode (5 * 4 bytes) + 1 byte to know
the actual position in the table
If the AMIS49587 is not synchronized the counters consist of 36 bytes:
1. The values of the real and imaginary parts of the signal for each frequency (I0, Q0, I1, Q1),
2. for the 4 last calculated timeslots (4 * (4 * 2 bytes) )
3. The current position in the board (1 byte)
4. The software reception gain (1 byte)
5. The hardware reception gain (1 byte)
6. The R_ALC value (1 byte)
