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 = 1, RM = 1). In this
operating mode, ALIS will decode and store the caller ID.
Figure 31 Successful Ring Sequence, No_auto_ring = 1; Caller_en = 1
Note: The RMR bit must be polled by the host to verify that the ringing signal is above
