The following chart and diagram show the successful flow of a ring-event detection with
no automatic power-mode change (No_auto_ring = 1, Caller_en = 0, RM = 1). In this
operating mode, ALIS will not decode the caller ID.
Figure 30 Successful Ring Sequence, No_auto_ring = 0; Caller_en = 0
Note: The RMR bit must be polled by the host to verify that the ringing signal is above
