necessary.
(*3) This IC is not proofed enough against a strong E-M field by CRT which mau cause function error

VCO tuning mode
TB1261 has two VCO tuning mode, which are
'Absolute' and 'relative'. The 'Absolute' mode refers
the crystal oscillation frequency 4.43MHz, the
'Relative' mode refers the IF input frequency, which is
tuned by AFT loop.
Set 'Relative' mode in normal receiving, and 'Absolute'
in channel searching. Even setting the 'Relative' mode,
the VCO
mode works as 'Absolute' in status of 'PIF Unlock'
automatically.

This mode is available only for the TB1262. This bit
set to L-system as to;

- Turn the modulation polarity to positive
- Delay the AGC time constant (Peek AGC),

with switching the IF AGC filter to the capacitor
of DCNF pin (10uF) instead of IFAGC pin
(0.47uF) .

- SIF AM demodulation (Split carrier only)

with switching the SIF AGC filter to the
capacitor of IFAGC pin (0.47uF) .

{L-SECAM AGC speed up}
Speed up the AGC response for channel search
{FM Stop}
Stopping the FM demodulator to use in NICAM

The read bus flags indicate that a certain signal is
detected at the moment. But reliability of detection
result is not so accurate if checking only one flag, that
confirming several flags, which means similar result
by each other, at the same time is recommended.
