bit 7-6 :
GRID [1 : 0] :
FM station search frequency interval :
0 = IFSD set
1 = 50kHz grid
2 = 100kHz grid
3 = 200kHz grid
bit 5 :
FLL_ON :
FLL Control
0 = FLL OFF
1 = FLL ON
During setting of the FM frequency and during seek, keep this OFF. Turn it ON after tuning.
bit 4 :
Reserved : 0 (Fix)
However, '1' is set when capacity is added to 16pin, and it uses it as Smoothing Filter(FLL_LPF).
bit 3-1 :
FS [2 : 0] :
Field strength setting at the time of FM station search and a frequency adjustment bit
Set 1 for setting of IFSD.
bit 0 :
SHF5DB :
Scan stop level +5dB

TARGET [15 : 8]
bit 7-0 :
TARGET [15 : 8] :
Target frequency High 8 bit :
Target value of oscillator calibration, Tuning frequency value or limit frequency value for station search
Note :
GRID [1 : 0] is not 0 TARGET [15 : 14] has different definition
With radio power ON, lower eight bits of the target frequency are set. Then, set higher eight bits of the target frequency to this register. The command is
executed.
