SM_IF : Command End interrupt flag
TUNED : Radio tuning Flag
Note : This flag is set when Tuned or a station search succeeded.
This flag is cleared under 3 conditions as below.
(1) PW_RAD = 0
(2) Tuning Frequency
(3) FM station searching
NA : 0 (Fix)
TUNEPOS [9 : 8] : Current RF frequency (High 2 bit)
REFPRE [2 : 0] : Reference Clock pre- scaler
REFMOD [4 : 0] : 5-bit slope correction
REFDIV [7 : 0] : Reference Clock Divider
REFOFFS [7 : 0] : Offset register for the spread of reference clock
