SIFLEVEL VIDLEVEL OPSTATE
1 = pin FREF works as reference frequency output
0 = pin FREF works as quartz oscillator or reference frequency input
1 = internal SIF level is reduced by 6 dB (only for AM sound)
0 = internal SIF level is normal
1 = internal video level is reduced by 6 dB
0 = internal video level is normal
1 = output port is HIGH (external pull-up resistor needed)
0 = output port is LOW
1 = pin MPP1 is logic output port; level depends on OPSTATE
0 = pin MPP1 is VIF AGC monitor output; independent on OPSTATE
1 = signal for external filter is obtained behind internal BP filter
0 = signal for external filter is obtained behind SIF mixer
1 = internal Nyquist processing off
0 = internal Nyquist processing on
