The following chart and diagram show the unsuccessful flow of a ring-event detection
because of no 2nd ring with no automatic power-mode change (No_auto_ring = 1,
Caller_en = 0, RM = 1).
Figure 32 Unsuccessful Ring Sequence, No_auto_ring = 1; Caller_en = 0
Note: The RMR bit must be polled by the host to verify that the ringing signal is above
