AA error threshold register
| HP_TRAIN_POSITION | when high use the bits just ahead of pdu for rsve training. when low the training bit starts at the track bits. |
| CORDIC_IN_SCALE | when high cordic input will be auto scaled(shift) according to the magnitude of real/imag data. |
| PAR_AUTO_HIGHER_SEL | when high par auto higher 1/4 when low par auto higher 1/8 it will work together with par_auto_higher_en and rssi_good_dbm. |
| PAR_AUTO_HIGHER_EN | when high when signal is good ( rssi large than rssi_good_dbm) it will auto higher the par threshold. |
| SNR_GOOD_TH | threshold for snr(fd mode calculated use aa) to reset datapath cooperate with cnr snr and aa error. |
| CNR_GOOD_TH | threshold for cnr to reset datapath cooperate with cnr snr and aa error. |
| RSSI_GOOD_TH | threshold for rssi to reset datapath cooperate with cnr snr and aa error. |
| RSSI_GOOD_DBM | when rssi dbm large than the -rssi_good_dbm the signal is good enough to higher the par threshold if the function enable. |
