10.5.10
The N1_LOSS_CNT and N2_LOSS_CNT counters to count the number of times the
signal is lost (LOS transitions from S5 to S6 in the Link State Machine) on Bands 1 and
2 are no longer supported.
Use the FAIL_CNT,
modem) counters to monitor signal failures instead.

The bits in this register are sticky bits that are set by firmware.
During Rate Adaptive (RA) process monitoring:

•
When the RA process monitoring is not active, all bits must be cleared to 0 by the user.
Preliminary Data Sheet
Firmware reads bits 0, 1 (SNR too high), bits 2, 3 (SNR too low) and bit 4 (BER too
high), to determine whether or not to rerun the RA process. Bit 4 restarts the RA
automatically. Bits 0 to 3 set bit RA_RERUN in register RA_STATUS.
Firmware clears bits 0, 1, 2, 3 and 4 after they are set.
The user must clear bits 0, 1, 2 and 3, to initialize them, before start of RA.
