DM_SE[1:0]
Bit 7 :
FLL_ON : FLL control
0 = FLL OFF
1 = FLL ON
Bit 6 – 4 :
CLKS_SE : Clock course select
0 = No select
1 = The source of the stereo decoder oscillator is effective.
2 = The source of the IF oscillator is effective.
3 = The source of the AM antenna oscillator is effective.
4 = The source of the FM-RF oscillator is effective.
5 = The source of the AM-RF oscillator is effective.
6 – 7 = no select
Note : Bit[6-4] selects the source of the oscillator. Select the arbitrary source that to be adjusted and to be measured.
Bit 3 :
nSD_PM : Stereo decoder clock PLL mute
0 = SD PLL OFF (Adjustment)
1 = SD PLL ON (Operation usually)
Bit 2 :
nIF_PM : IF PLL mute
0 = IF PLL OFF (Adjustment)
1 = IF PLL ON (Operation usually)
Bit 1 – 0 :
CM_SE : Command mode select
0 = Command no select
1 = Measurement mode
2 = Adjustment mode
3 = Radio tuning (reception frequency adjustment) mode
Note : This bit is used to select the command mode. Select the arbitrary command to be executed. The command is executed by setting
TARGET_VAL_L/H.
Command execution time :
SD calibration = 540ms
IF calibration = 134ms
RF(FM) tuning = 105ms
RF(AM) tuning = 158ms
* Stand-by at time to have provided for the above-mentioned before all processing including reading the register value after having
executed the command.

1 = The image bureau is evaded. (recommendation)
Bit 6 :
Reserved : 0 fixation
Bit 5 :
WAIT_SEL : Selection after tuning at mute release standby time
0 = 8ms standby
1 = 4ms standby
Bit 4 :
AM_FINE : Selection at AM_ANT adjustment standby time
0 = No standby after switch of DAC
1 = 2ms standby after switch of DAC
Bit 3 – 0 :
REFPRE[3:0] : Standard Clock Pre-scalar
0 = 1:1
1 = 1:2
