Bit 7 :
IM_STAT : State of image evasion code
0 = Eternal operation (It is possible to write it.)
1 = The image evasion is being processed. (Writing is improper.)
Note : This bit operates only when Resister 14h_bit7 (IM_EVAS) is set to "1". The data writing processing to LV23401 when this bit is "1" is prohibited.
Bit 6 - 5 :
IM_FS : Image bureau electric field strength
0 : Image bureau none
1 : 0
2 : 0dB to 10dB compared with the hope bureau.
3 : The level of the image bureau is +10dB or more stronger than that of the hope bureau.
Bit 4 :
MO_ST : MONAURAL/STEREO display
0 = Stereo reception (Compelling the monaural setting is also the same.)
1 = Receiving in stereo mode.
Bit 3 - 1 :
FS[2:0] : Field strength
0 : Field strength < 10dBμV
1 : Field strength 10 to 20dBμV
2 : Field strength 20 to 30dBμV
3 : Field strength > 70dBμV
Bit 0 :
TUNED : Radio-tuning flag
0 = No tuning.
1 = The tuning.
Note : When the frequency tuning succeeds, this bit is set. This flag is cleared under the following three conditions.
1. PW_RAD = 0
2. Do the tuning of the frequency.
3. When FLL becomes outside the correction range
Only when the TUNED flag is changed from one into 0, the RAD_IF interrupt flag is set.
When the status of TUNED changes from 0 into one, the interrupt is not generated.
Register 04h – TNPL – Tune position low (Read-Only)
