bit 7 :
RAD_IF : Radio interrupt flag.
0 = no interrupt
1 = interrupt
Note :
When status (field strength, stereo/mono) changes, this bit is set.
If Interrupt of IRQ pin is enabled, Interrupt pin is set by following IPOL register condition.
This bit is cleared by register read. In stand-by mode (PW_RAD = 0), this bit is 1
bit 6-5 :
NA [1 : 0] : NA 0 fixed
bit 4 :
MO_ST : Mono/stereo indicator
0 = Forced monaural
1 = Normal (Receiving in stereo mode)
bit 3-1
FS [2 : 0] : Fieldstrength :
0 = Low field strength
…
7 = High field strength
bit 0 :
SF5DB : Fieldstrength +5dB :
0 = FS5dB no UP
1 = FS5dB UP
For details, refer to Application note.
