AFCWIN
If no IF input is applied, then bit AFCWIN can be logic 1 due to the fact that the VCO is forced to the AFC
window border for fast lock-in behavior.
All standards except M/N standard.
M/N standard.
Typical time constant of FM carrier detection is 50 ms. The minimal recommended wait time for read out is
80 ms.

1 = VCO in 1.6 MHz AFC window
1 = VCO in 0.8 MHz AFC window
0 = VCO out of 1.6 MHz AFC window
0 = VCO out of 0.8 MHz AFC window
1 = black level detected
0 = no black level detected
1 = detection (FM PLL is locked and level is less than 6 dB below gain
controlled range of FM AGC)
0 = no detection
1 = after power-on reset or after supply breakdown
0 = after a successful reading of the status register
