EXTFILO
Not recommended in combination with internal IF level set to reduced (W4[7] = 1).
At internal Nyquist processing off (W7[0] = 1) it is mandatory to set the internal video level to normal
(W7[4] = 0).

1 = mute
0 = normal
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 = logic output port; level controlled by bit PORT1 (W7[3])
0 = monitor output of VIF AGC voltage
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
